[JDEV] fixed bugs in wcs

[Stefan Strigler]

Hi there,

I'm developing a javascript based web client using the wcs component.
Unfortunately I found some (many?) bugs in there and fixed them. What
I've done so far:

wcs_js.c:
* wcs_js_iq_roster didn't handle groups correctly
* _apos only escaped ', it now escapes \n and \r too (think there is
still more too escape)
* the sid wasn't returned correctly

wcs_sid.c:
* fixed error on login

wcs_cache.c:
* the "cache" was organized such that new message got added to the front
of the list. this is completely unhandy as order of messages gets messed
up. So I add messages to the end of the list.

Does anyone still maintain this component? Is someone interested in my
patches?
