Wowarmory XML fetching

As a result of the comments about the stability of the data fetching from the WOW Armory, I’ve made some changes to how it is done.

Resynchronization should now be a lot better working. They (Blizzard)  haven’t documented their IP banning policy, so I can’t be sure. If you still have 3 or more consecutive resync failures while the Armory is working fine, please post.

A lot of bugs pointed out in the previous entries’ comments should also be fixed, for example Fury Warrios now incur an additional 2% penalty to their gear score. Sorry guys
