Cleaning up the bug tracker

[Johan Tibell]

Cabal hackers,

With 477 open issues, it's hard to use the bug tracker efficiently
e.g. for prioritizing work. Gregory Collins and I have started
cleaning up some dead bugs. We won't get through all of them, so I
encourage other to join in a try to reproduce bugs and add a note to
the bug if it's reproducible or not. Feel free to drop me an email if
there are any bugs you think could be closed.
