Possible duplication of database configuration files.

As @heusch pointed out, we have similar database configuration files in two places. Initially I suggested just to delete identical files, but after a closer look I realised that files are actually different.

For example we have:

bob/pad/face/config/database/msu_mfsd.py

and

bob/pad/face/config/msu_mfsd.py

Both are registered in setup.py, but in different groups.

One here: 'bob.pad.database': [ 'msu-mfsd = bob.pad.face.config.database.msu_mfsd:database',

Another one here: 'bob.bio.config': [ 'msu-mfsd = bob.pad.face.config.msu_mfsd',

As far as I understand first entry point allows to run experiment as follows:

spoof.py --database msu-mfsd <other arguments>

Second one is actually a full DB config allowing to run experiments easier:

spoof.py msu-mfsd <other arguments>

The question here is: should we try to get rid of one of these config files, or do we keep both?

I think one of these files can actually be removed, preserving functionality mentioned above.

@amohammadi Can you please advise on this? Thank you!
