* Remove package name
* Start with upper case letter
* Remove trailing period
Also reword some descriptions and move some long descriptions to
longDescription.
I'm not touching generated packages.
Here are four patches. Three of them add expressions for games. The
fourth, irssi-perl.patch, adds perl as an input for irssi, so that one
can run perl plugins in irssi. I didn't make the perl input optional,
but maybe it should be to keep the irssi expression light.
