Moved most of the functions that contained "window.doSomething" that were located at:
- app/assets/javascripts/application.js
To the following file:
- app/assets/javascripts/lib/utils/common_utils.js

The functions listed here:
- window.ajaxGet
- window.split
- window.extractLast
- window.rstrip
- window.disableButtonIfEmptyField
- window.disableButtonIfAnyEmptyField
- window.sanitize
- window.unbindEvents
- window.shiftWindow

Now will be accessible from the "gl.utils" namespace

Integrates changes from ClemMakesApps' commit:
8581e152, although it was reverted to avoid frustrating conflicts.

See MR: !5530 (diffs)

This reverts commit 8581e152.

This creates really difficult conflicts with another MR that was
worked on simulataneously. That MR mostly encompassed the aims of
this commit.

Currently trees are sorted in the fashion:
- folders
- files
- submodules
with each section sorted alphabetically

This changes to this system:
- folders and submodules (sorted together)
- files
