Show tags in commit view
### What does this MR do?
With this MR you can see the assigned tags for a commit in the commit view.
### Are there points in the code the reviewer needs to double check?
I don't think so. But it would be awesome if the reviewer can tell me how to add a tag to the sample_commit in spec/support/repo_helpers.rb.
Then I can add a test for the new tag_names_contains method as soon as possible :)
### Why was this MR needed?
At the moment if one click on a commit will see details such as: parent commit, amount of additions, deletions, but will not see if this commit has Tag linked to it.
Showing branch, tag details will give better overview about the commit

This MR adds syntaxhighlighting to the email-on-push notifications.
## Are there points in the code the reviewer needs to double check?
No
## Why was this MR needed?
Currently the diff in email-on-push notifications is just a monochrome diff that's hard to read.
This MR adds colored syntaxhighlighting to the mails.

Remove password strength indicator
We were having the following issues:
- the indicator would sometimes stay red even if the password that was
entered was long enough;
- the indicator had a middle yellow signal: what does that mean?
- the red/green backgrounds were not color-blind-friendly.

I decided to create a fork of rouge as rouge lacks a HTML formatter with
the required options such as wrapping a line with <span> tags.
Furthermore I was not really convinced about the clarity of rouge's
source code.
Rugments 1.0.0beta3 for now only includes some basic linting and a new
HTML formatter. Everything else should behave the same.

Flatten the directory hierarchy while there is only one directory descendant
In some languages, especially java, the directory structure reflects the package structure.This means that using the file tree browser to reach the directories that matter you have to click a lot of directories containing only another subdirectory.
This merge request tries to enhance this by showing and providing the link to the first directory that doesn't contain only one directory.

This is very similar to what [GitHub does](https://github.com/blog/1877-folder-jumping), but I don't think graying out the empty directories is really necessary.

I'm actually very new at ruby, rails, haml, and almost everything involved in Gitlab's development...
From what I could understand, when we render each directory item in the list we only have the data structure representing the item but not his descendants.
To iterate through the hierarchy I call Gitlab::Git:Tree.where() but I'm not sure if this is the most efficient way.
I also considered making every directory a clickable link, but I tried that and in the end it wasn't very useful and reduced the click target for the most useful directory.
