Toss in a couple other scripts, written quite a long time ago

1. compare-ssh-fails
- read /var/log/auth.log to extract SSH failures, compare the
- origin IP addresses with list of blocked IP's from "ufw status"
- and print summary stats with blocked/not-blocked info

2. show-git-commit-summary
- pull commit messages from a starting and ending hash, can be things
- like "-5 head" and not just actual hash values.  The output is shown
- in a simple, easy to read format

3. parse-access-log
- AWK script to read Apache common log format files and only display
- the selected fields.  Documentation would be nice for this one...
