Buffalo-classic

Buffalo version 0.7.0:

* Major refactoring of the entire spell tree. This fixed some minor spell selection bugs (and probably introduced some others)
* Added: Learning new talents or changing spec (Anniversary) now updates the UI.
* Added: Omen of Clarity for Balance Druids
* Removed support for WotLK after Cataclysm took over. No, I do not intend to play Cataclysm or Mist of Pandaria.

* Fixed selfie buffs position: now aligned with label.
* Fixed LUA errors during initalizing when an "unsupported" class (e.g. a Warrior) logged on.
* Fixed LUA error when learning new spells as an "unsupported" class.
* Fixed a LUA error when handling Warlock's Demon.

* Fixed Class configuration: window size was sometimes set wrong.

* Fixed Class configuration: missing class icons after login.
* Bugfix: 6/5 in PrayerBuffs forced default 4/5 to be used when reloading addon.
