Fix clone URL losing selection after a single click in Safari and Chrome

### What does this MR do?

This MR deactivates the mouseup event in the `git clone` URL to prevent the text from being deselected after a single click.

### Why was this MR needed?

In Safari and Chrome 43.0.2357.65 (42.0.2311.152 worked fine), the URL would lose selection after a single click. To reproduce:

1. Go to https://gitlab.com/gitlab-org/gitlab-ce
2. Click on the URL in the repository (HTTP is selected by default).
3. Click on the SSH button.
4. Click on the URL again.

The URL selection should be selected automatically, but it is deselected immediately.

It appears that 92544df8 changed the selection event from `click` to `focusin` to make copy & paste work in X11. This Stack Overflow article discusses the deselection issue in detail:

Add Accepted and Rejected tabs to MR lists.

Before, MRs were referred to as Merged or Closed, but the Merge button on the MR page read "Accept Merge Request", the activity feed even read "X accepted merge request Y", and the Closed tab on the MR index included both Merged _and_ Closed MRs. I've changed every occurrence to consistently refer to MRs as either Accepted or Rejected, which is less technical and more clearly two opposites.

[ci skip]

Allow HipChat API version to be blank and default to v2

### What does this MR do?

This MR fixes a regression introduced in v7.11 that requires a HipChat API version to be specified when it is supposed to be optional.

### Why was this MR needed?

The "optional" HipChat API version in 57c72455 passed in a blank `api_version` when nothing was specified, and the code was not tested. This would cause a 500 Error.

### What are the relevant issue numbers?

ADD: Note on how to setup dns hostname resolution to installation manual

Hi,

I'm suggesting to add the following note to the installation instructions. It took me some time to figure out why the test failed and why I wasn't able to push. The error messages did not point into the right direction so this might help other people with the same problems.

I hope my english is good enough, if not, please feel free to rephrase anything.

Thank you in advance,

Holger Segnitz
