* more player interface (but it's still beginning)
* int3 members public
* more usage of int3
* adjusted animation speed
* reversed changes from rev.165 in CPreGame - it wasn't bug, it just works so. That change was breaking a few things in CPreGame and was needless - Player ID == Player's Color. I thought it was obvious.
* minor stuff
* creature set now uses std::set
* int3 class - may be used for locations
* fixes crashbug in cpregame (state in HughButton not initialized)
* started making CTownInstance
