This patch adds support for the OTR protocol to irssi. This is an import of the external irssi-otr project that we are now taking over maintership for. Major thanks to the original authors of Irssi-OTR: Uli Meis and David Goulet. Thanks to the OTR community in #OTR on OFTC, thanks to everyone who have helped testing the patches and submitted UI suggestions.
