Standalone coordinate don’t connect to waypoint lines

Standalone coordinate don’t connect to waypoint lines

Both altitude and acceptance radius will track last value

- New mission command editor dialog
- New MissionCommands toolbox object to get command info
- Added APM mission item set

Also friendly editor for MAV_CMD_NAV_ROI and MAV_CMD_DO_SET_SERVO

Also turn on MavlinkLogTest

Instead us a Toolbox concept which hangs off of QGCApplication

Too unstable for CI at the moment
