Added test project for the eclipse plugin
Added a way to generate and get the workspace ID

I also added a test to test that we I do generate a valid ID (non empty) and to make sure that it's always the same (for the same workspace)
Added the workspace ID in front of the changed resource path

See title. It's descriptive enough
Merge pull request #11 from caiusb/workspace-id

Added the workspace-ID to every changed file
