Make scons work on mingw/windows, from Bo Peng (ben.bob@gmail.com)

* SConstruct: force the use of g++ under windows, and use the right libraries 
	* config/qt4.py: check QtGui4 etc as well.
	* src/SConscript: link to the right libraries
	* src/tex2lyx/SConscript: use the right libraries
	* src/frontends/qt3/SConscript: manually moc .h files under windows
