Title: Allow configuration of the sed command to be used.

On OS/X, the builtin sed command does not handle the sed expressions
used throughout git-prompt.sh. This commit allows customization of
the sed command to use in git-prompt.conf. On OS/X, one could install
GNU sed instead (e.g., brew install gnu-sed) and modify sed_cmd to use
that.
