Fixed Renamer functions, QuickChange UI

Renamer functions SnipTextBefore and SnipTextAfter now behave properly
when the text isn't present, and snip correctly.

QuickChange comment added for ArrayImport.  btnOk and btnCancel now
centered.

CCOR Compatibility script "Globals copied" message moved after the
globals have been copied.
Armor Mod Builder update, Mator Smash Beta

Armor Mod Builder now has a button for selecting the meshes directory.
This is a lot more intuitive than typing a relative path manually.

Mator Smash is a simple script which allows for the creation of
rudimenty Bashed Patches.  It's currently not customizable and doesn't
have any tags, so conflicts are handled in a single way that maximizes
data.
