Corrected some stuff and tweaked models and offsets again. Added gib impact sounds (Droplets compat). Made Translocator module throwing work like in UT (same math, even). Corrected sludge wall sticking, uses projection now rather than a cheap trace.
Allow armor/pads to replace shield belt when it's not at max capacity (emulating UT behavior).
Recalculated all the model transforms in preparation for coelckers/gzdoom#495. Corrected some small mistakes in Dual Enforcers code.
All weapon pickup models have been added in. Modeldef has been subdivided to make things easier for me.
