Remove obsolete README.Qt5

Qt5 is fully supported now, and installation instructions have been
in INSTALL for a while, so the old README.Qt5 can go.

-Qt5 Support in Quassel IRC
-==========================
-
-As the Qt5 alpha release is around the corner, I've started to play around with it
-mostly to see how much effort the porting of Quassel would be. It turns out that there
-was no porting effort at all; after adding support for it in the build system
-(which led me to clean up a lot of the Qt4-related mess that has been in there forever),
-fixing some bugs that were hidden before, and cleaning up some #includes, all of the code
-seems to just compile and mostly work. In particular, none of our black voodoo and QMeta
-abuse broke with Qt5. Additionally, you can freely combine both Qt4 and Qt5 clients and cores.
-Well done, Qt Team!
-
-To enable building against Qt5, pass -DWITH_QT5=1 to cmake. Note that Qt5 (the bindir) needs
-to be in your current $PATH unless you have installed Qt5 into one of the usual system locations.
-
-At this time there are a few known issues:
-
-* Some of our optional dependencies don't exist in Qt5 versions and thus need to be disabled
-  (most of them are forcibly disabled in the build system). This includes QCA (QtCrypto) support,
-  DBusMenu, libindicate, and unfortunately also KDE. As new versions of those show up, we'll
-  enable them again.
-
-* The Quassel UI looks rather fugly with Qt5, at least on my box, as there are no style plugins, no
-  themes, no desktop integration. Well, enough for a proof of concept, I guess.
-
-* The CMake files for Phonon shipped with Qt5 are buggy, so linking fails. No Phonon support at
-  this time.
-
-* SSL does not seem to work in the server currently. You might have to pass -DWITH_OPENSSL=0 to cmake
-  to make it work at all (try this if you don't get a connection from your client).
-
-So, feel free to play around, let me know about issues, but be aware that this is not in any way
-tested or supported at this time.

-Cheers,
