papers status -v will tell you file count in the bibtex

[boyanpenkov]

Small change to get papers status -v to account for every file in the bibtex, so you can be sure that at least the numbers of files in the filesdir and bibtex are the same.

Aaand my mistake, sorry -- this is branched off the wrong branch, it also contains #92.

The relevant changes are just to config.py -- this can wait until #92 goes in, or I can break them out separate.

Sorry about this.

Basically, makes it look like this:

papers configuration (global)
version 2.3.dev273+gaca948e1e
* configuration file: /home/boyan/.config/papersconfig.json
* cache directory:    /home/boyan/.cache/papers
* absolute paths:     True
* backup (git):       True
* backup files (git-lfs): True
* backup directory:   /home/boyan/.local/share/papers/backups/home-boyan-vazhno-work-literature-library
* files directory:    /home/boyan/Vazhno/Work/Literature/Organized (128 files, 247.5 MB)
* bibtex:             /home/boyan/Vazhno/Work/Literature/library.bib (128 files in 126 entries)

Or I can squash this into #92 ? Again, sorry abut this.
