updated and expanded authorship file

[ThePeach]

Hi and thanks for the work done on this repo.
I've taken the liberty of updating and expanding one of the scripts in order to extract a bit more information from the files.
I've also added a bunch of flags to control the output: it can now return:

• the authors (as it was before)
• the files and the list of authors ordered by number of commits
• the files ordered by total number of commits
• the files ordered by total number of commits with the list of authors ordered by number of commits.

while still be able to filter the files by extension.

I have not much experience in Ruby, but it did make sense to me to reduce the number of requirements for this simple script.

Let me know if there's anything you'd like to have it outputted differently or updated/refactored in a different way.

git isn't an acronym.

Thanks for the work here, and sorry re the delay in responding. I'll have to dig into this, but if I use it, I'd definitely rename basic_stats. It's a very general name, and, when sitting next to a file named file_stats, also takes on some redundancy. The -o option is much faster than tally_authors, although other flags seemed slower in a large repo (informal, groggy, early morning assessment here; no actual benchmarking done).

thanks for the reply @gilesbowkett, feel free to take whatever you need from it, also if you want I can jump in and adapt some of this into something more specific if you prefer.

@gilesbowkett I've done the required changes (a bit late, but here you go) and fixed the merge conflicts.
