archive 6.x-1.3

- Calendar block now displays part of the previous and next month along with the current month.
- archive.css is now included by the block module.
- Dates that are not in the current month have a class of "out-of-month" and are colored a light grey.
- The calendar block has been updated to use more semantically correct HTML (caption and thead).
- The size of the calendar block has been reduced slightly.
- Archive should now play nicer with postgresql, though there may still be some issues.
