- Implemented legacy field mapping for columns and sort fields.
- Implemented rc.indent.report.
- Implemented rc.row.padding.
- Implemented rc.column.padding.
- Implemented rc.color.label.
- Modified default rc.indent.annotation from 1 to 2.
- Implemented urgency value caching.

- Columns now know which report thy belong to, so they can use the
  rc.report.<report>.dateformat override.
