Fix GeminiBuster producing tinted GeminiShots.
Reorder SecondMap rendering to reduce texture bindings. Remove unused
code in SecondMap. Reduce difficulty of SeeteufelScreen second area and
SeeteufelSide. Enforce a minimum delay between ceiling attacks for
SeeteufelSide. Restore sounds and particle effects that were previously
removed for testing. Reduce number of particles generated by some
entities. Stop some sounds from playing before playing them again, such
as Bomb explosions. This helps lower the total number of concurrent
sounds playing, improving performance. Fix bug in WatchNadia affecting
hit box size. Fix bug in SeeteufelSide causing the music to continuously
start and stop after SeeteufelSide is defeated. General cleanup.
