[mythtv] Latest CVS changes to mythmusic require Qt 3.1.1

[thor]

	Latest CVS updates to mythmusic (cdrip.cpp) make calls to a QString member 
that is not available in Qt 3.0.x (specifically QString.replace(char, char)).
	
	Upgrading Qt to 3.1.1 (latest) solves this. 

	When upgrading, remember (at least) Qt ./configure flags for mysql support 
(-qt-sql-mysql) and threading (-thread) (you may also want -qt-gif, 
-qt-xinerama, -fast, etc.). While you're upgrading, try and make sure that 
qgl is being supported (ie. you have OpenGL headers and libraries available) 
as there are some upcoming mythmusic visualizations that require it. Remember 
to change your qt symlink and/or update your QTDIR environment variable.
