[Plugin] XMPP Notify plugin for 1.2.3

[wsw70]

(copied from bitbucket in case someone has a better idea)

Thank you for this plugin -- it works fine and is very useful.

It would be great if there was a way to configure the status:

• ideally in a dynamic way with some useful info like the number of downloads/seeds/...
• or at least statically -- in particular with the option not to have any status displayed

Thanks!
