Set most UI to disabled by default with it only enabled on the addition of an active UAS. Added all missing parameter control buttons to the Vehicle Config widget.

Change for conditionally displayed config items (based on other params), and fix for layout of some config items

Addition of new "User" param for apm.pdef.xml file, allowing for sorting config entries between general and advanced tabs

Added a new QGCTextLabel type for QGW files, which can display MAV text or hardcoded text.
Added tabular configuration screens based on folder structure inside the files/autopilot/airframe folders

Configuration parameters are now split into two categories, General and
Advanced, where General parameters are anything defined in the
configuration file and Advanced are anything not defined in the
configuration file, but the autopilot still returns when requesting a
parameter list.
