add branch name to the commit message -- go to .git/hooks/prepare-commit-msg and replace the file

# Automatically adds branch name and branch description to every commit message.
# Modified from the gist here https://gist.github.com/bartoszmajsak/1396344

# This way you can customize which branches should be skipped when
# prepending commit message.
