Long time ago it's was used without prefix to make future switch from boost to std version easier.
I discusses this with Ivan and decide to drop these using from Global.h now.
This change wouldn't break anything because there was already code with prefix for each of three cases.
- use std versions of function, bind and ref
- OVERRIDE -> override
- NULL -> nullptr
- use std versions of random distributions
NOTE: this may be last revision that supports gcc-4.5
- support for one more Russian localisation, fixes#1321
- fixed icon for level 1 town hall, #1294
- correct portraits for first heroes from mods, #1297 and probably #1298
And a lot of gcc compile fixes
* BattleAI will restore callback to its previous state, fixes freeze after battle #1104
* BattleAI won't lose turn when unable to correctly evaluate a spell
* VCAI will correctly recognize hero standing on town entrance
* War machines of defender will have correctly set side
* Faction 9 as neutral causes crashes, changing to -1 as used elsewhere in the code
* battle AIs receive ptr to CBattleCallback (not sure why it was CPlayerBattleCallback, likely mistake)
* reworked some battle callback methods to be more generic and able to handle some hypothetic scenarios
* for testing purposes in duel mode the first AI will be taken fro mconfig and the second will remain stupid ai
* minor changes
