Carbine UI Fixes

Core

Load fixes as their own addon so I don't have to pass every event through like OnSave and OnRestore.
Added the ability to add a last active version for fixes to stop them from loading once the patch is live.
Added 'active' flag to fixes.
Deleted defaults button from config window since there are no configs.

ContextMenuPlayerFix

Added lastActiveVersion as it will be patched today.

WhisperFix

Prevent the standalone addon from loading rather than this one.
