Task System (preliminary work)

[Derision]

I've started to document how the system works on the Wiki, the overview page links to the pages I've written so far:

There are still some Perl interfaces to be written, and a few tweaks to the tables, code cleanup and testing (robustness against bad data in the tables, discovering the limits on the number of active tasks, task selector entries, completed tasks, etc, that I can send to the client without it crashing) before it will be ready for an alpha release.
