Title: Git-plugin: Dirty should count the number of dirty files (instead of being on/off)

It doesn't cost much more to actually get the number of dirty files instead of knowing if the current repo is considered as dirty.

This change could imply the removal of everything related to ``clean_formatted`` as clean would just be dirty with a value of 0.
