After seeing the coveralls report I realized the projects were not
relocatable. While this might be convenient for some uses, moving a
project from one place to another might not be optimal. This has been
changed now.
The only place where absolute filepaths are handled now is with flat
project layouts. However, it is possible to overwrite this filepath if
the targets folder is to be changed.
The generate_repository_data script works in the exact same way as the
generate script and it generates a fresh batch of pre-signed metadata to
test the load_project function.
