Slate TPanelChildren, TSlotlessChildren are no longer full-fledged arrays; removed any unused Array API.
Fixed up a lot of improper use cases.
This better encapsulates the action of adding/removing Slate Widgets from the runtime tree as a Slate Core concern.
Alows us to add parent pointers in the future with significantly less effort.

The settings editor now queries the appropriate source control state of files that it its editing, rather than using the read-only state (which is only applicable to Perforce).
Also added a throbber to indicate that a source control query is in progress.

Please note that file comments had no purpose in nearly all cases and just added visual clutter. The two files that had meaningful file comments had their comments moved into the corresponding classes. There are still hundreds of file comments left in other files that will be removed over time.
Also cleaned up some random stuff along the way:
- relative paths to public headers within the same module are no longer necessary (automatically discovered by UBT now)
- header guards are deprecated, use #pragma once instead (all compilers support it now)
- space between multiple template brackets is no longer required (all compilers support >> now)
- NULL to nullptr, OVERRIDE to override
- spelling errors, whitespace, line breaks
