Render control feature: shader-level shadowbuffer bias

Lampbuffers require painful bias tweaking (to prevent aliasing or to
get shadow detail). Sometimes you want this different per object, like
for gras you want less shadow detail, but for the ground you want high
detail. This feature allows to tweak it.

The new "LBias" slider is in shader panel, bottom. Ugly! But, thats for
later...
