Spoike 0fee3a4aea Add ortho lights (still has serious issues that make them unusable on regular maps). 
First real attempt at lit water.
Parsing rtlights is now aware of spotlights.
Default cl_yieldcpu to 1, to save cpu for anyone who sets cl_maxfps lower. Added to menus.
presets now include view angle clamping - maps made for quakespasm REQUIRE full pitch angles despite it otherwise being considered a cheat or glitchy (on servers that try to block the cheat).
fix r_fullbrightSkins>=1 issue.
