-updated logic_script entity icon
-info_particle_system now starts enabled (start_active = 1)
-fixed default teamspawn model settings
-added SetModel, SetCycle, and SetPlayBackRate inputs for all dynamic model entities that support them (spell pickups, teamflags, prop_dynamics, etc.) These only work in TF2.
-added clarification to func_nav_avoid regarding the use of tags. Thanks to Elizabeth!
-Added target keyvalue (entity to point at) to all light entities with angles, so you can aim them that way. Let me know if this breaks anything.
-added placement helpers to path_track, similar to cubemaps
