Motivation for this change

Updates QGroundControl to the latest version and makes it work correctly using the new QT mkDerivation.

I removed a lot of dependencies that I could not find any reference to in the code, as well as some that were only required by features which are not enabled by default.

The only issue I know of with this package is that it is unable to detect its version number, so it is shown as "None". This occurs because the build system attempts to extract the version number from git. Even if the leaveDotGit parameter is passed to fetchgit, the build system ends up extracting one of the tags fetchgit creates instead of the correct version number tag.
