First iteration, and some stuff is missing. But basically this rake task
does a clone of a project we've pointed it to. Than creates a project on
the GDK, which should be running in the background. This project is
exported, after which we move that archive to the location we need it.
We clean up by removing the generated project.
The first idea was to export the project on .com too, however than we
might run into ImportExport versions mismatch. This could've been
circumvented by checkout out an older commit locally. This however is
not needed yet, so we opted to not go this route yet, instead we will
iterate on what we got.
