upgrading language-python to 0.5?

[Tycho Andersen <tycho@tycho.ws>]

Hi,

Is it possible to upgrade the version of language-python in sid? 0.4
doesn't build with ghc 7.8, and I'd like to update some of my code to
work with it and not have to patch it for debian :). I'm happy to help
if that would be useful.

Thanks,

Tycho
