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
### What are the relevant issue numbers / Feature requests?

Add placeholder values to hipchat service
This MR adds placeholder values to the hipchat service.
This should prevent issues like #279 or #772 that popped up because people didn't know what exactly they are supposed to enter in the fields.

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.

Make search for projects case insensitive
### What does this MR do?
This MR makes the search for projects case insensitive.
### Why was this MR needed?
Currently the search for projects is case sensitive.
You can test this on gitlab.com with the search string "perforce" for example.
* perforce returns 2 projects
* Perforce returns 5 projects
* PERFORCE returns 0 projects
This makes it harder to find the projects you are looking for.
With this MR users can find more projects, since they don't need to worry about not seeing some projects just because of an upper letter.
@dblessing Can you take a look at this? :)
