Deprecating Old Amarok Versions

[Nate Graham]

In general I think a policy of deprecating Qt4-only software makes 
sense. Qt4 has been or is being removed from distros and nobody supports 
it anymore. Apps that didn't get ported after all these years are, for 
all intents and purposes, abandoned and dead. We can un-deprecate them 
if anyone ever decided to port them, but until then, I support 
deprecating all Qt4 apps--including Amarok.
