[games-strategy/hedgewars] correct dependencies

[jauhien]

Server needs dev-haskell/zlib.

[hasufell]

strictly speaking we should do a revbump for corrected dependencies, since wrong dependencies can have side effects for people who have either dynamic dependencies in portage deactivated or use paludis

but since this is an overlay, I guess we don't need to be that picky

thanks for the correction

[hasufell]

Oh, now that I see it.. I think dev-haskell/zlib is build-time only, since we have static linking in gentoo haskell. Can you check that?

[jauhien]

Oh, really, I was not aware of static linking. Let me see, but it seems you're right. I'll fix it in a moment.
