Support configurable attachment size in Application Settings page
### What does this MR do?
This MR provides the ability to configure the maximum size of an attachment inside a note. A parameter has been added to the Application Settings page.
### Are there points in the code the reviewer needs to double check?
What should be done with the legacy note attachment validation? I added code to make the validation work with the configurable setting. I could see an issue where an admin lowers the limit from 10 megabytes to 5 megabytes, which could cause an existing model to be invalid.
### Why was this MR needed?
We often have attachments that exceed 10 MB, and it would be nice to be able to override the defaults.
### What are the relevant issue numbers / [Feature requests](http://feedback.gitlab.com/)?
See Issue #1258

See merge request !407
Updated projects.md to show tag_list field when performing GETs
Updated projects_spec.rb to include check for tag_list key in project list
Added changes to the CHANGELOG
Import GitHub, Bitbucket or GitLab.com projects owned by authenticated user into current namespace.
Addresses #1347.
Untested since I'm in a bit of a hurry. Will definitely have time to test and add unit tests before the 7.10 release :)
See merge request !481
Don't allow username to end in period.
The current behavior doesn't do username referencing and mentioning in sentences like "I discussed with with @douwe." since `douwe.` is matched as a username.

Ability to skip some items in backup
https://dev.gitlab.org/gitlab/gitlabhq/issues/1936
Now it is possible to run
```
sudo gitlab-rake gitlab:backup:create SKIP=repositories,uploads
```
available options: repositories,uploads,db
See merge request !470
If a filename happened to contain "db" and enough "rwx" characters before, then
this test would previously fail. For example:
```
drwxr-xr-x gitlab-runner/gitlab-runner 0 2015-04-02 07:46 uploads/tmp/cassidy.stokes8477/gitlabhq/36d972fa55d6b44810fc6fd843473adb/
```
Adding a space before the "db" match string tightens up the regexp and reduces the
chance of unintended match.
For view port sizes between 1260px and 1200px pixels the event-title was
too wide, thus not truncated and got pushed into a second line.
100% - 174px was chosen as the max-width because 141px is the widest
.event-item-timestamp can get (with 'less than a minute ago') + 24px for
the avatar + 8px avatar margin + 1px to fit into the gap.
Unbind task item checkbox events and then rebind them
Fixes#1340
This issue was caused by this line: https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/projects/issues/update.js.haml#L17
`new Issue()` gets called on every JS-based issue update, and all the binds in the constructor get re-applied without first unbinding the existing ones. Right now my fix is *only* for the checkbox events, and I suspect there are similar issues still present for other events.
