Big thanks to @Warpten, he joined my project and helped a lot.

IMPORTANT NOTE: Read / append packed time functions in ByteBuffer.h are not correct, they need to be fixed in order to have event times accurate

Following improvements:
- Spellscript for crystal spikes
- Spawn crystal tanglers with spell
- Usage of event map
- Correct usage of frenzy
- Heroic spells
- Target selection for crystal tanglers

Details for the spell script:
There are 4 spells. Each of them spawns the same trigger but in another direction. The trigger gets an aura which triggers the spell which summoned him after 250ms. This time is too long, so it triggers on apply. Don't worry - test ingame first, it's working blizzlike (I watched some videos on YT to find out which is the best amount of time difference between spawn and next summon).

Some summon types don't store the spell id which summoned them. The trigger is one of them which are not doing so. So I had to move the line, which stores the spell id in the summon out of the if. This could be done more specific, but it works fine. This improvement is required to find out which spell the aura applied to the summoned trigger has to cast to keep the right direction.
