also reduces amount of headings with only a single entry
SendAirStrike() - now listed under "Support Powers"
Guard() - now listed under "Combat"
FindResources() - now listed under "Movement"
Deploy() - now listed under "General"
SendParaTroopers() - now listed under "Support Powers"
Paradrop() - no listed under "Transports"
Teleport() should probably be listd under "Movement", but I don't know how to change that (currently listed under "General").
note that I changed "ScriptGlobal" to "ScriptPropertyGroup" for SendAirStrike() - I hope that does not screw up anything
