* dismiss Hero works blocked in the castles
* the backpack scrollable arrows aren't available (yellow, clickable) even when backpack is empty.
* added missing info texts for buttons in hero window (and added functionality of enable tactic formations button)
* can select (single click) and enter castle (double click) from the map. Same for hero.
* Hero gets automatically selected after End Turn
* Hero is automatically selected when exiting town
* In Garrison or Hero army: units are selected when we first click on them
Fixed (at least partially) also a problem with disappearing path
Because of really huge amount of modifications here I've probably missed some minor stuff. I doubt if it's still compatible with gcc - some changes should be reapplied.
* 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
