Merged dev changes 10/24/2019

- Applied the nexttoken security fix (suggested by ficool2, important for MP port, no #ifdef MAPBASE because of volume of changes and irrelevance to readers)
- Fixed a crash with the follower wait point start/stop using handlers
- Fixed game_ui activator crash
- Changed vphysics triggers to accept more entities
- Fixed player squadmates not obeying hint node facing (e.g. wait points)
- Fixed npc_snipers
- prop_vehicle_jeep_old no longer changes classname
- Restored and added the other CTakeDamageInfo fields for point_damageinfo
- Fixed game_metadata not saving correctly
- Fixed logic_measure_movement not functioning while possessing spawnflags
- Added scripts/mapbase_rpc.txt script with choosable app ID and game image
- Fixed some casing that broke Linux support
- Added proper WorldVertexTransition blending to translucency and selfillum (translucency may need the translucent texture to be $basetexture, not $basetexture2)
- Added modified parallax corrected cubemaps to shader code (although currently unusable)
- Fixed Variant_ParseInput
- Added/restored custom scanner speed (experimental, needs more work)
- Several miscellaneous code changes/fixes and comment adjustments
