Android: Support the extraenvvars and extraappparams options

The Qt/Android runtime does support passing parameters to the
application. We have to pass '-e extraappparams <base64 string>' and
'-e extraenvvars <base64 strings, concatenated by ";">'. This is very
handy and should actually be exposed in the GUI.
