Stuart Buchanan f09b49e006 FG1000 : APR and GS modes 
Approach and GS modes - FG1000 and GFC700 can now be used for
autopilot coupled ILS or GPS approaches

Also:
- FLC mdoe now include an airspeed bug
- VDI indicator beside altitude tape now works
- Marker beacon displays O/M/I as appropriate

<!-- AP/FD logic is somewhat complex:
1) Pressing AP toggles the autopilot on/off
a) OFF to ON : OFF-AP-ROL transition below
b) ON to OFF : Handled by a separate FSM. We could use a series of transitions
to the same states below, but that would result in entry bindings being repeated, which would be bad
2) When the AP is enabled, the FD button is disabled. (Easy - no transition!)
3) Pressing the FD button when the FD is enabled switches off the FD : Switch-off transition below
