Implemented validation and printing of all supplied repositories (#24).

Upon start-up, now directly passes all supplied paths to git in order
to check if all of them point to a valid git repository.

The clone.create() function now returns a list of Repository instances,
containing the name and location of the repository. This is later
used in the gitinspector module to execute and parse the repository.

format.output_header(...) now takes a list of Repository instances.
Thanks to this, each output format can print every supplied repository.
