5.0.0-beta1

After some years and a couple of alpha releases we have a beta.
Well.. it's marked "beta" but you'll probably find it pretty much stable.
Several people have worked on the codebase and ultimately on this release.
Many of them hang daily around #kvirc@Freenode. Come and say hi! :)

Have fun!
