Mimic pending param support by just calling through to setParameter.

Also updated to latest QGCUASFileManager implementation.

Also restructured signals to be more command-centric as opposed to
ui-centric.

Added:
- sequence numbers
- better filtering for image encapsulated data messages versus FTP
- directory list now contains file sizes
- open command now returns file size in data

Tried to order items in order of importance.
Also all perspectives now have their own shortcuts.

Both on the backend (replaced with DEFAULT view) and on the front end (removing UI menu items).

Includes removing an if-statement that should've been dead but was erronously applied to the following statement. Dead code = bad, if-statements without braces = bad.

This was deprecated on Febuary 3rd, 2014 and removed a little later. This finally completes that process.

Without this, when you go to airframe config and the current config is
Simulation it will not be selected. Hence you won’t know what the
current config is.

Specifically much better testing for the handling of:
- Ack responses not being sent by server
- Getting Nak’s back from commands
- CRC failures

Also changed file validation to take into account Mock Server no longer
sending file length in first byte of file.

Also changed the downloaded file contents to not include the file
length in the first byte. This makes the code a bit less confusing.

Changed to get the current voice properties, then modify then and set new ones.

When unit tests are being run in TeamCity the host box can end up being
very bogged down with other builds. So need to up wait time, to take
into account CPUs grinding.

Need to disambiguate from video stream messages
