show git branch in prompt/terminal

found here: http://www.jonmaddox.com/2008/03/13/show-your-git-branch-name-in-your-prompt/

I made small modifications to fit my liking:

function parse_git_branch {
git branch –no-color 2> /dev/null | sed -e ‘/^[^*]/d’ -e ‘s/* \(.*\)/(\1)/’
}

function proml {
local BLUE=”\[\033[0;34m\]”
local RED=”\[\033[0;31m\]”
local LIGHT_RED=”\[\033[1;31m\]”
local GREEN=”\[\033[0;32m\]”
local LIGHT_GREEN=”\[\033[1;32m\]”
local WHITE=”\[\033[1;37m\]”
local LIGHT_GRAY=”\[\033[0;37m\]”
case $TERM in
xterm*)
TITLEBAR=’\[\033]0;\u@\h:\w\007\]’
