Subject: Wait for it...
X-Git-Tag: 0.4.0~305
X-Git-Url: https://git.quassel-irc.org/?p=quassel.git;a=commitdiff_plain;h=0d2e5ff7439fe7bf9f24f1f55763881382ecb12a

Wait for it...
introducing /wait. Usage: "/wait 5; hi there" Will send the message "hi there" to the current buffer after 5 seconds.
wait is a non-blocking call.
