Changes in the engine in recent patches.

Looks like blizz doesn't want to document all the things they do to us:

- SetUnitX/Y no longer crash outside of bounds.
- UNIT_STATE_LIFE < 1.0 event now triggers after (PLAYER_)UNIT_EVENT_DEATH also, none of those events is able to detect buffs.
- Special Effect natives no longer need .mdl in their paths to work, looks like .mdx works as well, haven't tested without extension.

The first one is cool.
The other are not that special (are they?).

The UNIT_STATE_LIFE thing shouldn't have been changed :c

Second one screws up some old spells and systems badly.

state == 0.00 trigger after

state == 0.01 trigger before

soo you still can detect buffs on death.

it doesn't matter, there's still a change in how that worked.
