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.

Dir should not be 0, but set it to 1 if 0 in case I missed some other place this was done. Also correct cloud scaling.

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.
