A Time Before Time

Release 0.3.1

- Use strtol on user-supplied dates. We can now use dates up to
Gregorian 9223372036854774641 (Erisian INT64_MAX (9223372036854775807)
- Handle dates BCE
- Handle dates before the Original Snub. As far as I know, there is no
official term for this era. I have arbitrarily dubbed it "BS": "Before
Snub". Use %z/%Z for abbreviated/full era names.
- Check default $LOCALDIR data location $HOME/local/data
- Fix potential stack smashing in ddate_fmt
- Fix various bugs found by scan-build
- ddate_fmt now correctly checks for St. Tib's Day brackets:
previously, ddate "+%{foo %{bar%}" on St. Tib's would yield
"foo St. Tib's Day"; now, ddate elides starting at the first curly
bracket.
- Implement 21 ways to fail. We just need two more!
