User interface changes:
- Fixed crash that can occur while editing or saving rule.
- Fixed crash when editing a rule using attributes that are no longer supported.
- Pattern editor window should no longer appear in lower left corner of screen. Happens when one drags (even slightly) instead of clicks on the pattern field.
- Fixed pattern field not expanding when item is dragged in (as opposed to typed or inserted by clicking on them).
- When editing a format pattern, example text now shows a date for custom date attributes.
- Various other fixes and tweaks.
