- Fixed bug where '6 months' was interpreted as 180 days, but when rendered
was shown as '5 months' (thanks to Aikido Guy).
- Multiple unit test corrections.
- Added support for more type-specific checks of attribute values.
- Added support for more type-specific attribute rendering.
- Improved generalized methods for checking columns in a report.
- Added unit tests.
- Minor code cleanup.
- Added secret hidden feature for internal testing.
- Removed support for ' 1 wk', namely spaces before and after the ordinal.
This removes (some) ambiguity in more complex command lines.
- Fixed unit tests accordingly.
- Allowed durations to be specified numerically as seconds, in string form.
This flexibility allows the removal of special-case handling that stores
recurrence periods in raw form ('monthly'), reducing code size. As a
consequence this means that recurrence may now be rendered according to
Duration::formatCompact, which is desirable.
- Added supporting unit tests.
