1.0 released.

GOM saves/restores raid arrangements, and can also auto-arrange based on class/spec. Auto and Restore are one-click, no spamming a macro repeatedly, and if you hit Auto it can do the talent scan and the arrange without anything else from you. If you want to change the rules the auto-arrange follows, you can make templates for it (it comes with one for AV and a general one for PvE raids).
Any feedback/criticism would be great. Especially on the auto-arrange since there are lots of views on how players should be arranged; or if you want to suggest a template (or make one) that you think should be included with the addon.
