git hook to copy config files.sh

# Git hook to switch config files made for a Rails app
# Looks for config file named like the branch. 
# 
# i.e.:  database.mybranch.yml 
# 
# If the file is found, copies that to the actual config 
# overwriting the previous one.
# 
# The third parameter is 1 when we are switching branches 
#
