Moving on to eclipse jdi, getting rid of tools.jar dependency

This removes processing's dependency on sun jdk's tools.jar for running sketches and uses eclipse's jdi implementation instead. 

The following files need to be added to processing/app/lib folder:
* com.ibm.icu_4.4.2.v20110823.jar
* jdi.jar
* jdimodel.jar
* org.eclipse.osgi_3.8.1.v20120830-144521.jar

You can find these in the processing/experimental/mode folder.

Update: I added the jar files. **No need to copy** them anymore.

P.S: This is purely experimental, bugs are to be expected.
