* battle AIs receive ptr to CBattleCallback (not sure why it was CPlayerBattleCallback, likely mistake)

* for testing purposes in duel mode the first AI will be taken fro mconfig and the second will remain stupid ai
* minor changes
- town screen is mostly implemented, has some minor issues
- factions are now separate from towns, neutrals have faction with id=9
- more constants to GameConstants: town-specific buildings, strings for terrains and resources
- replaced most access to builtBuildings with isBuilt() method
- replaced id's with enums for town subtype and buildings id's
* Updated MSVC project files
* Filesystem: My version of .SND archive does not have \0 after WAV extension. Fixed (though hardcoded 3-char extension length).
* New bonus types: BLOCK_MAGIC_ABOVE for blocking casting spells above given level and BLOCK_ALL_MAGIC for blocking all magic.
* Heavy rewrite of battle callbacks. Fixed some minor bugs. Code reusage between lib/client/server (removed proxy calls). Better access control and support for various perspectives.
* Fixed#1031
* Fixed Orb of Inhibition and Recanter's Cloak (they were incorrectly implemented). Fixed#97.
* Fleeing hero won't lose artifacts. Spellbook won't be captured. Fixed#980.
* Fixed crash when attacking stack dies before counterattack (ie. because of Fire Shield)
* Server does some basic checks if action requests during battle are valid
* Minor stuff.
Fixed issue where cursed ground obstacles were appearing on holy ground (and vice versa).
Fixed battle interface blocking itself up after clicking on owned stack to open creature window.
Now obstacles should be placed exactly like they were in OH3.
All problems with displaying obstacles in battlefield should be gone. They should be now matched to the single pixel.
If there are still some discrepancies, please report them.
