Core/Dungeon Finder: Some optimizations.

- Store teleport coordinates to avoid recalculations each time someone has to be teleported
- Correct teleport error msg when player is charming or using vehicle
- Internal changes in storage types
- Proper code for missing achievement lock type
- Better debug msgs
- Trying to get rid of "Player*" and "Group*" inside LFGMgr as much as possible (Step 1)
