Good example for usage of new mock uas interfaces and implementations.

Realized that I had configured my APM:Plane incorrectly since
FlightModeConfig was only set up to work with APM:Copter. Changed code
to respect mode switch channel parameter across all APM frame types.
Also a pile of other changes to make this code much more bullet proof
and correct. Implemented simple mode as well. Changed the style of the
code to be more data driven. This allows for adjusting for new param
values without needed to changing any code.

Allows for testing of existence of lack of existence of signals coming
out of an object.

Used for unit testing

This allows us to create mock version of the objects to use for unit
tests

I have UI based unit tests coming, so getting ready for that

- NAN not available in windows headers, use cross platform friendly
version
- VS compiler does not allow initializing non-integral types in header
files
- ActiveQt libs are already installed by Win Qt4.8.5, no need to build.
Plus this part of the makefile just loops without nmake.exe installed
which is not part of a standard windows box

Converted LinkInterface from a pure-virtual interface into an abstract base class. This centralized the data rate calculation code for all subclasses. Also added the necessary code to provide upstream/downstream data rate calculations for all LinkInterface-derived classes.

Renamed getNominalDataRate to getConnectionSpeed. Also added upstream/downstream data rate functions to all Link classes.

Simplify calculations by assuming we only care about rates in kB/s.
