[oi-dev] 1576 update irssi package, attempt 2

[Josef 'Jeff' Sipek]

Here's attempt #2:

http://hg.31bits.net/oi/oi-build-irssi/rev/76d6998dea83

I dropped one of the JDS patches since oi-build has a manpage stability
mangler.

The weird /usr/include/irssi/src is weird, but that's how it's supposed to
look like.
