new feature, a flag for notifications -n /
--notify. It's using the notify-send command line utility to send
desktop notifications. By default I made it compatible with dunst (you
will need to enable full markup in the dunst config) but it should work
with other notification daemons too.
* use getopt_long(3) and support short options
Now instead of `--format`, `--no-fancy`, and `--help` you can also use
`-f`, `-n`, and `-h`. Additionally instead of just being able to do
`--format <fmt>` you can now do the standard `--format=<fmt>`.
* remove initial space when m_bFancyOutput is true
* add the HSL format
* add the HSV format
* add a manual page
* silence compiler warning
* make all the default target, and add install rule
* add the CMYK format
* add new formats to the README
