[kde-freebsd] Testing KDE 4.2

[Bartosz Fabianowski]

Yes, you can have both installed at the same time. The only thing I
don't know about is where KDE4 writes its configuration to - I installed
it a couple of days ago but have not run it yet. If it uses ~/.kde, then
you want to log out of KDE 3, move ~/.kde out of the way so KDE4 cannot
mess with your settings and then move it back if you decide to switch to
KDE 3.
