It should be possible to list only resources attached to a particular bob.bio.XYZ implementation

Created by: anjos

As of today, all installed resources are listed on the screen.

If a user, for example, is going to run face recognition experiments, but bob.bio.spear is installed on the environment, all resources with for both packages will be listed.

It would be nice to have a command-line option on resources.py to filter out stuff that you're not interested on. For example:

$ ./bin/resources.py -dt database --package=bob.bio.face

Would, in this case, list only the resources for the bob.bio.face package.
