Fix git blame syntax highlighting when different commits break up lines

### What does this MR do?

This MR fixes a bug where syntax highlighting would not work properly in certain lines when doing a `git blame` view of a file. Also, this MR reuses the Rugments lexer and formatter for each `git blame` commit block, which should make things faster and reduce overhead.

### Why was this MR needed?

When doing a `git blame`, GitLab feeds the Rugments lexer/formatter blocks of code based on the latest commit for each line.  However, this can cause lexer to fail because the state is cleared between each block of code, which causes `highlight` to fallback to the plaintext lexer. For example, notice this unhighlighted line in [this file](https://gitlab.common-lisp.net/cmucl/cmucl/blame/master/src/assembly/assemfile.lisp):

The fixed version looks like this:

![image](https://gitlab.com/stanhu/gitlab-ce/uploads/32c4d7c8ff15a7d59b364dd988f7c657/image.png)

This MR requires a patch to rugments to allow the `continue` option to be passed to the lexer.

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:
