src/Viewer/FGEventHandler.cxx: NewGUI::setStyle(): added code to rescan style files.

Browse source 
Changing style will reload style from filesystem, so one can edit styles and
see results without restarting fg.

Note that this duplicates initial populating of /gui/styles/ from
defaults.xml's <sim><gui>...</gui></sim> section, so it's a bit of a hack.
