Provide a Web client for the new deployment

[aszlig]

Currently, we have two available Web clients, one is jwchat and another one is Jeti. The latter seems to be unused and also nowadays really nobody really wants to run a Java applet in the browser, so we can drop it without replacement.

So, we only need to have a replacement for jwchat, either stay at it or move to an alternative like Jappix.

@devhell suggested to take a look at Kaiwa.

I'll also add Candy, conversejs, and jsxc.

IMHO jsxc currently looks like the best canidate, because it does support Jingle Audio/Video and allows for website integration.

+1 for jsxc

[aszlig]

+1 again for jsxc, because this is used in diaspora... in case we want to run a pod ;-)
