Register math fonts with Qt 4.2 or higher. Using Qt 4.1, the old

Browse Source 
xft-fonts package is still required. However, on *nix there seem
to be no way to tell fontconfig to prefer our fonts instead of
others matching the requirements, so, in case of conflict, the
fontconfig files should be manually adjusted, or some existing
font package used (note that the quality of the bakoma fonts is
better than that of the xft ones). There is no such problem on
Windows where our private fonts are always preferred over the
installed ones (and I hope the same holds true for Mac).

	* src/LyX.cpp
	(LyX::exec): don't call addFontResources() and restoreFontResources()
	anymore, as the frontend code will do the job.

	* src/frontends/qt4/GuiFontLoader.{cpp,h}
	(GuiFontLoader::GuiFontLoader): register math fonts with Qt.
	(GuiFontLoader::~GuiFontLoader): unregister math fonts.

	* src/support/os.h
	* src/support/os_unix.cpp
	* src/support/os_win32.cpp
	* src/support/os_cygwin.cpp:
	remove code dealing with fonts.

	* configure.ac: don't check for fontconfig headers anymore.
