Diver - Count commits by contributors

[pylapp]

User story

As a software forge admin
I want to compute the number of commits by contributors in a project
So that I will be able to give dumb and useless KPI and some figures to management (and have some ideas about amount of commits)

Related to #153

Details

• Use this script list-contributions-by-contributors.sh
• After having generated the files with commits by authors, just run some wc -l command on each file
