For whatever reason, showing the dialog through a function causes a crash in QML (undebugable--new word!)

Internet available now has a signal

- Don't allow goto click while other guided ui is visible
- Use NoMouseThroughRectangle for guided ui popups
- Better visuals for goto indicator in map

Adding mux GStreamer plugin libraries to Android (to enable video recording on Android)
Adding an option to limit the amount to disk used for saving videos
Adding an option to show/hide the REC button (allowing plugins to handle the recording in their own way)
Adding simple frame grab to file

- Altitude slider not showing up
- Continue mission not showing up in action list

Update the user model to a single controller instead of multiple

Added a bit more separation between the Toolstrip and the Toolbar

Fixed a pile of bugs as well
