Add Jetty Subproject

[ryantxu]

This adds the libraries and a simple launcher to run waffle within jetty

Coming soon... a jetty Authenticator and LoginService based on waffle

On Jetty, I thought it was a simple servlet-compatible container. Do we need to do anything special for it (Authenticator, etc.)?

[ryantxu]

eep -- i clearly still have a lot to learn with git/github. I tried to make #15 only point to the changes here:
https://github.com/ryantxu/waffle/commit/b375306cc56261d850d568a91ac888a457fc7b05

Not all the changes -- I guess I need to make a pull request from a fresh checkout.

Yes, Jetty is a simple servlet container. Like tomcat if you use the ServletFilter, there is nothing special to do. Like tomcat it also has its own Authenticator classes.

The stuff I added here is really just a trivial starting place. The only real thing is a utility class that lets you run the server from a command line or directly within eclipse.

It may not make sense to merge this 'till there is anything specifically jetty related, but I personally find running a webserver in debug mode very helpful.

Having a web server that developers can run in debug mode would be helpful. Please re-add Jetty via ivy (the new way to fetch dependencies), and make sure to document what one is supposed to do with this. README is probably OK.

I'm going to close this for now, but a nice small clean PR is welcome.
