[JWebUnit-development] Adding sample logback.xml to JWebUnit homepage

[jevon <je...@je...>]

Hi,

In r951, I've added some brief instructions on how to get the logback
logger to be quiet - by default, if no logback.xml is present, then
ALL logging information (including on-wire transmissions themselves)
will be dumped onto stdout. I've hit this problem twice now so I think
it's probably a good idea to include it in the quick how-to guide.

Thoughts? I haven't pushed the changes onto the SF homepage yet (I'm
not sure if I have the permissions anyway).
