Added "Average" as scope math function.
Changed averaging window size text edit box to be active only when math functions are selected.
Fixed bug introduced immediately prior by removing child redefinition of saveConfig.
Tried installing scroll wheel event filter for scope config plugin, but is not currently working.
This will allow us to build a parent project for
qt-creator that sits above both openpilotgcs and
uavobjgenerator so that we can build both projects
at the same time.
