Integration with messaging service like IRC, XMPP

[NikolaiPatrushev]

Personally i would like to see a plugins for the integration with encrypted messaging services like IRC and XMPP.
The nodeBB should be a "relay point" serving all those incoming messages and sending back the responses from users.

Then we need working poll voting plugin, which can be used anonymously in tor network and in normal internet.

Then plugin which actually play video in the topic like flash player in former times of youtube, current plugins play videos but not as embedded video player.
