• Looked into the deadline date bug. Turned out it was caused by the actual dates on tasks being wrong (tasks for early months of next year had 2006 deadlines).
• In the process of fixing that, decided that deadlines should be displayed in a useful manner.
• Added code to put deadlines in brackets after post titles in the report.
• Added more code to check the date of deadlines, and for tasks with status Outstanding, where the deadline is passed, display dates in red.

David helped a lot with this; I discovered I'd been doing some risky things in PHP (associative arrays using integer index values), so we switched them to strings for the sake of stability. David also helped debug a stupid error of mine (= instead of ==).
