Changed output for each repo in gitall

Hi Walter
I am a very fond user of your gitall script after my company recently moved to git (I had/have my own hgall script (also hosted here on GitHub) that I used previously, so I was happy to find yours to use after the switch.

I recently modified my local copy of gitall, so that it only prints the name of the repo (=subdir) instead of the absolute path for each repo. I also added colouring (currently pink) to this (for me) very important piece of info.

I hope you like my addition and would consider this pull-request.

Regards Jan
and greetings all the way from Copenhagen, Denmark
