Fix Script Naxxramas/Gothik with help of scarymovie87

Fixes issue #80.

- Implement support for "merging" life and dead side after ~2 minutes, if group is not splitted
- Implement support for opening central gate at 30% boss health
- Implement Gothik teleport between side when above 30% boss health
- Fix dead-side mobs spawn in 25-Man difficulty
- Fix waves setup.
- Fix some timers (this may still need some tuning).
- Fix sporadic combat reset when Gothic teleport to ground.
