Cumulative patch:
Fix RF_MODELLIGHT (was broken and dont work same way engine does it).
Fix bug in physics_ode_constantstep 1 (integer division, huh).
Added new geomtype field for ODE physics - sets collision shape, SOLID_PHYSICS_ are not deprecated (but keeped for compatibility reasons), as geomtype is a more correct way to set collision shape (allows to set both SOLID_CORPSE and trimesh collisions for instance).
Fixed support of custinfoparms.txt as some recent change in shader code seemed to broke it.
