Hamburger: Delete, Delete All, Show all Values

There are many ways of iterating over lists in C++/Qt.
In the specific case of QStrings, it is known [1] that using
foreach with const references avoids the creation of new
QString objects in each iteration, reducing the time consumed
by the loops.

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
