Fix invalid Atom feeds when using emoji, horizontal rules, or images
This is a fix for issues #880, #723, #1113.
Markdown must be rendered to XHTML, not HTML, when generating summary content for Atom feeds. Otherwise, content-less tags like *img* and *hr* are not terminated and make the Atom XML invalid. Such tags are generated when issue descriptions, merge request descriptions, comments, or commit messages use emoji, horizontal rules, or images.
To pass this option through from the relevant Haml templates to the proper place in the `gfm()` method, a new method `gfm_with_options()` is introduced. It reuses the options dictionary passed to `markdown()` and interprets options `xhtml` and `parse_tasks` from it (the latter was a convenient replacement for `gfm_with_tasks()`). `xhtml` is already interpreted by Redcarpet::Render::HTML, but that alone was not sufficient, because the post-processing in `gfm()` would convert its XHTML tags back to HTML.
I found no way of passing additional optional options to the existing `gfm()` method without requiring updates to existing callers and without getting in the way of the existing optional arguments, but maybe someone who knows more about Ruby than I can think of one.
Thorough review appreciated since this is the first time I have used Ruby.

Change permissions on backup files
Use more restrictive permissions for backup tar files and for the db, uploads, and repositories directories inside the tar files. See #1894. Now the backup task recursively `chmod`s the `db/`, `uploads/`, and `repositories/` folders with 0700 permissions, and the tar file is created as 0600.

Restricted visibility levels - bug fix and new feature
This allows admin users to override restricted visibility settings when creating and updating projects and snippets, and moves the restricted visibility configuration from gitlab.yml to the web UI. See #1903.
## Move configuration location
I added a new section to the application settings page for restricted visibility levels. Each level has a checkbox, styled with Bootstrap to look like a toggle button. A checked box means that the level is restricted. I added a glowing text shadow and changed the background color for checked buttons because the default styles made it hard to distinguish between checked and unchecked. This image shows the new section with the "Public" box checked:
## Allow admins to override
To allow admin users to override the restricted visibility levels, I had to remove the `visibility_level` validation from the `Project` class. The model doesn't know about the `current_user`, which should determine whether the restrictions can be overridden. We could use the creator in the validation, but that wouldn't work correctly for projects where a non-admin user is the creator and an admin tries to change the project to a restricted visibility level.
The `Project::UpdateService` and `Project::CreateService` classes already had code to determine whether the current user is allowed to use a given visibility level; now all visibility level validation is done in those classes. Currently, when a non-admin tries to create or update a project using a restricted level, these classes silently set the visibility level to the global default (create) or the project's existing value (update). I changed this behavior to be more like an Active Model validation, where using a restricted level causes the entire request to be rejected.
Project and personal snippets didn't have service classes, and restricted visibility levels weren't being enforced in the model or the controllers. The UI disabled radio buttons for restricted levels, but that wouldn't be difficult to circumvent. I created the `CreateSnippetService` and `UpdateSnippetService` classes to do the same restricted visibility check that the project classes do. And since I was dealing with snippet visibility levels, I updated the API endpoints for project snippets to allow users to set and update the visibility level.
## TODO
* [x] Add more tests for restricted visibility functionality

Execute hooks and services when branch or tag is created or deleted through web interface.

Fix code preview theme setting for comments, issues, merge requests, and snippets
User color scheme was not being used: default white color scheme was always chosen. Also, default background for code in notes was always overriding the user color scheme.
Closes#1139
See merge request !357
Generate valid json
This patch helps to be compatible to other programing languages as it improves the validation of hook data. It seems only ruby can handle 'nil' as value while other json decode function will fatal.
See merge request !182
Also preserve code preview color scheme in events dashboard.
Assign default colors to all code blocks shown as <pre class="code highlight [color_scheme]">
Closes#1139
Add new service classes to create and update project and personal
snippets. These classes are responsible for enforcing restricted
visibility settings for non-admin users.
Automatically link commit ranges to compare page.
Closes#2103
Implemented as proposed in the last paragraph of the issue:
> We could do something similar to Ruby, where `1..5` means `1,2,3,4,5` and `1...5` means `1,2,3,4`: `..` means inclusive, `...` means exclusive. In our case, `sha1...sha4` would mean `sha2,sha3,sha4` (exclusive with regards to `sha1`) and `sha1..sha4` would mean `sha1^...sha4`, i.e. `sha1,sha2,sha3,sha4` (inclusive to `sha1`).
- `sha1...sha4` now links to `compare/sha1...sha4`
- `sha1..sha4` now links to `compare/sha1^...sha4`.

Ruby str_equal uses memcmp internally to compare String.
Memcmp is vunerable to timing attacks because it returns early
on mismatch (on most x32 platforms memcmp uses a bytewise comparision).
Devise.secure_compare implements a constant time comparision instead.
Supports four different event types all bundled under the "note" event type:
- comments on a commit
- comments on an issue
- comments on a merge request
- comments on a code snippet
