reworked GIT_NOTIFY_PATTERN with inchck
Changed NO_COLORIZE to COLORIZE

- Fixed all of the various command's GIT_NOTIFY_PATTERN, so that when
  the correct pattern is seen, command output will be shown
- Added note about colorization being disabled when output is to a pipe
- Set an EXIT_STATUS at the top of the script, and renamed STATUS_EXIT
  to be EXIT_STATUS
