* Implement talent specs switch functionality.
* Only gossip part still not implemented.
* At update server to this commit or later character talents will be reset
with some spam in logs about wrong places talents in character_spell.
It can be ignored as part of conversion to new table support.
Thanks to all getmangos.com community members who take part
in creating and updating original dual spec patch.
