Started a simple test

Added a test case and a small project to test my assumptions on.
Renamed the test
Added jdt.core as a del for the eclipse plugin
Added a jar to the test project
The test and method to get the libraries that are outside the workspace
Added the correct assert
The getInitialSnaphot now returns the path of the zip file

So I can test the whole thing easier
Renamed the test project

Also, the set-up method is now called only once, before all tests are run.

Since I don't change the project, rewriting it every time is a bit wasteful.
Initial implementation of the libraries addition code

So far it fails because it rewrites the zip file.
Fixed the test

No it uses the correct method
Copying the existing entries into the new file

And then renaming it to the old one.
Reactivated the file sender

This shouldn't have gotten it...
Merge branch 'refs/heads/master' into libs
Merge pull request #33 from caiusb/libs

Getting the libraries that are not in the workspace
