Pass light sources in blue channel of vertex color instead of decoded light for all special drawtypes.
Plus some style fixes and optimizations.

Config settings:
profiling = true/false (gather statistics)
detailed_profiling = true/false (break mod times to callbacks)

Chat commands:
save_mod_profile saves current statistics in debug.txt and shows on console (on default loglevel)

The fix didn't work on some systems sadly this wasn't detected prior merge,
as preload is disabled by default now there's not gonna be a fix for it.

Skip shading for lightsources and top of the nodes.
Fixes liquid sources and flowing surfaces having different brightness.

This can delay connections by several minutes.
