Version 1.1

This release introduces support for OpenBSD. The configure script is now
used on all platforms, and depends on pkg-config or pkgconf. Unnecessary
warnings when compiling with gcc are now silenced.

The /ignore command and option can now match on message contents.
Ignored messages are no longer scanned for URLs. The current topic can
be copied by pressing tab twice after /topic.

Scrolled up windows remain in the status line when not active. Mentions
are now coloured up to the first occurence of ": " rather than ":".

Parameter handling for list mode commands and MODE messages from the
server have been fixed.
