Checked in Jetty embedded server

[Andrew Jaquith]

Hi all --

Just checked in a class called TestContainer that embeds a Jetty  
webapp container. I wrote it to automate web unit testing so that it  
doesn't require a separate Tomcat server.

TestContainer could, with a little refactoring, be made to work as a  
small, embedded server for out-of-the box use. I've not got the time  
to polish it for that, but I'd encourage anyone who wants to do that  
to give it a try.

In the meantime, the Ant 'webtests' target has been massively  
refactored and made -- I hope -- fairly goof-proof. Give 'webtests' a  
try!
