* fixed crash when there was no hero available to hire for some player

* pregmae wont crash if user gives wrong resolution number
* fixed 1024x600 screen resolution
* selection dialog (eg. for treasure chests) can be closed with enter key
* orientation of hero can't be change if movement points are exhausted
* numerous improvements for Tavern window (hover tips for buttons, button will be inactive if player has 8 heroes or there is a visiting hero in the town garrison)
* campfire, borderguard, bordergate, questguard will be accessible from the top
* spells not known by hero can't be casted
* restored checking mana points before casting spell
