Required due to webapp classloader changes in Jetty 7,
we can no longer access or extend Jetty classes.
- Extend javax HttpServlet instead of Jetty's DefaultServlet
- Implement BasicServlet to replace functions of DefaultServlet
- Add MimeTypes implementation to add to servlet's defaults
- Add local mime.properties file, remove checks in I2PSnarkServlet for those
we were missing
- Eliminate all use of Jetty utility classes including MimeType, Resource,
Buffer, Cache, URIUtil, ...
TODO:
- Use servlet path everywhere, so the war can be renamed
- Don't override service()
