Filter up_all_from_url() (#29)

Adds two filter arguments (`-only` and `-skip`) which can each be
provided with files (in the same format as the produced logs).

Skip simply skips any entries in the file which are also in the
provided make_info output.

Only skips all entries other than those in the provided file.

Also:
* Minor change to test output
* Documenting -test argument in usage
