major rewrite of the foundation:

- de-maveniziation (uses the same code that Acre uses to drive jetty directly)
 - removed all dependencies on external javascript code (jquery and suggest) by making a local copy (this makes gridworks totally self-serving, meaning that you can use it even if you don't have any internet connectivity)
 - fixed a NPE when the servlet is shutdown before any project is loaded
 - found a way to spawn a browser directly from the java code (untested in windows)
 - added two ant tasks to generate windows and macosx stand-alone binaries (unused just yet)

To run, just type "./gridworks run" at the command line
