started implementation of hover and cruise distance

corrected typos

prevent survey from crasing

added checks for vtol

rearrange logic

added primitive check for landing

rearranged checks

new arrangement

added logic for transition

fixing the stats display

enable hide/unhide of vtol and survey stats

adding check for surveying item

Conflicts:
	src/MissionEditor/MissionItemStatus.qml

removed comment
