Level Transition Fix

Fixed level transitions using resetState
skeleton for level loading changes
Progress!

Particles and lights, as well as others?, added properly into FlxGroups.

Particles and emitters reworked. Lights reworked.  State and level
transitions fixed.

TODO.
Incorporate DAME properly.
Change level transition blocks into zones.
Maybe look into preventing enemy respawning yet again.
Check and, if needed, rework collision/overlap code.
