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.
This code belongs to callback because both player and AI shouldn't directly access information about teleport channels.
For example pathfinder code need to check teleport channel type only based on information about objects player already seen.
- removed hoverText field
- split getHoverText() method into 3:
- - getObjectName() for generic name
- - getHoverText(Player) for player-specific text
- - getHoverText(Hero) for hero-specific strings
