Directional lighting tweaks (#1833)

changes:

Flashlights now default to LIGHT_WIDE directional lighting.
Glowsticks, Lamps, Flares, and Slime Cores use LIGHT_OMNI.
Maglights use LIGHT_NARROW.
Heavy-duty flashlights use LIGHT_SEMI.
EVA suits default to LIGHT_WIDE.
Lanterns use LIGHT_OMNI, as well as now having a more appropriate light color.
Floodlights use LIGHT_WIDE, as well as having a more appropriate light color.
Synthetics default to LIGHT_WIDE. (including drones)
Added some predefined light_wedge values to the lighting defines file.
Fixed some bad angles that screwed up north/south lights in some cases.
