Small testing app for DrawMap scene

Some basic functionality

Initial commit of the Draw Map Scene

add a uid to VGs for purpose of Lua manipulation

corrected steps

Add a visual gear for drawing circles. Intent is to allow specifying areas on map for lua scripts (such as to indicate a location to go to). Could also be used to, say, circle a hog in CTF. Also add a "Critical" flag for visual gears so a gear flagges as such will always be created.

fix for frontend desync
