Arsenal - Favorites System

[LinkIsGrim]

When merged this pull request will:

• Add a favorites system to the arsenal.
• Make FUNC(refresh) public, add parameter to skip updating current/unique items.
• Fix tooltips for the menu bar not showing unless a button or the menu bar area was clicked last (hovering over the buttons will kill search bar focus, though).

Default mode can be controlled by CBA Setting, so can the highlight color. I'd go for icons instead but we'd have to either overwrite mod icons if an item is favorited or make left panel a listnbox as well (and it would be cluttered on the right panel unless its width was increased).

EDIT: Now that this works, I've tried out using icons. The ones available in vanilla look ugly as sin, and clutter is still a problem, particularly with magazine names.

Favorites can be added/removed by double clicking an item while holding left shift and are saved to profileNamespace.
Still works with sorting/searching.
Current items (including inventory) are also displayed in favorites, without the highlight color.

Favorites are always saved in lowercase to prevent them being affected by configCase changes (mod pack changes or updates).

Since alpha is modified for the right panel (in case the item doesn't fit), I opted for this solution instead, but it's a bit dirty.

That should be all the bugs handled (besides the search bar losing focus if you hover over a button in the menu bar).
