Support supressing text file diffs on the default branch with .gitattributes

This change allows users to suppress diffs for text files by adding an entry to the `.gitattributes` file. To take effect the file present at the HEAD of the default branch.

When rendering a diff, if the file is text according to the charlock holmes gem (via the `text?` method) but the file is not diffable according to the project repository, then a message is displayed stating that the diff was suppressed.

I looked into ways to do this using a `binary` flag as suggested by @stanhu in [this comment](https://gitlab.com/gitlab-org/gitlab-ce/issues/2315#note_4435454), however, there was no good way to seperate what was a real binary file from one that had been marked as not diffable in `.gitattributes`.

Fixes and closes gitlab-org/gitlab-ce#2315.

This button depends on Issue#can_be_worked_on? which in turn depends on
Issue#related_branches. By rendering this button asynchronously we can
finally remove all usages of Issue#related_branches and
Issue#referenced_merge_requests from the issues "show" page.

Enable the UrlFormat and UrlQuotes SCSS Linters.

There were no lints to fix for this one, so it's just preventative.

UrlFormat: URLs should be valid and not contain protocols or domain names.

UrlQuotes: URLs should always be enclosed within quotes.
