load condition for guild name

[mm-051]

Is your feature request related to a problem? Please describe.
When playing multiple characters in different guilds that use different WA packs, it's frustrating to keep them updated separately and for my raid team to juggle different versions between guilds, esp. when some of the raiders aren't WA-savvy.

Describe the solution you'd like
A load condition option added for the current players guild name, similar to the currently implemented load condition for character name.

Describe alternatives you've considered
N/A

Additional context
Implementing this will allow guilds to have their own custom packs that are set to load for characters in that specific guild, not interfering with characters in any other guilds. This will help the less WA-savvy players.
