also adds AMSL output in ft

Path through code allowed for xmlfile to be used when file was not
opened. Also changed qWarning->qDebug to allow QT_FAIL_WARNINGS to be
used to find bugs.

This allows us to run with QT_FAIL_WARNINGS to find bugs. Also temp
comment out of failed signal connection.

This prevents a threading problem where previously the new happened on
the wrong thread.

This way we can test with QT_FAIL_WARNINGS set.

Plus a few API tweaks

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.
