TEA Roll helper

New features:

- Added critical wounds to party display (only people with updated addon will send this info).
- Added 'Utility type' select to Utility action tab. Selecting a type for which you have a bonus (eg. Intelligence for Gnomes) will apply that bonus to your roll. This is only shown if it's relevant for your character.
- Added Utility traits to character config. These are free-form text fields that can help you remember which ones you've set. You can select which utility trait to use (if any) in the Utility action tab.
- Added small section in Heal action tab for removing critical wounds.

Roll system updates:

- Added Feat: Trauma Response
- Added Trait: Greater Restoration
- Added Weakness: Old Scars (does nothing... for now)
- Implemented Racial traits: Arcane Affinity (High Elf), Diplomacy (Human), Entropic Embrace (Void Elf), Expansive Mind (Gnome), Inner Peace (Pandaren), Mastercraft (Mechagnome)
- Added custom Feat: Vengeance (Callean).
- Renamed Calamity Gambit to Veseera's Ire. If you have this trait it will change automatically.

Other:

- Party UI is now hidden if party is empty.
- Fixed roll type buffs applying to every turn type instead of the specified one.
