Image Speak - More Contribution and UI

Archenemy has contributed again! Thank you! This time new skins for the bear, giant spider model and new portraits! Very nice bunch of contributions. :-) The Party Behavior screen is now mostly done and working. I've started to create the player initiated encounters' preencounter group selection window now (nice name, isn't it?), it's almost ready. All in SVN. Press F2 to toggle Party Behavior screen.
