- Crew monitoring computer using the html_interface module

- Patch: Don't update html_interface clients that have been inactive for more than 10 minutes.
- Patch: Attempt to speed up _renderContent some more (in case of multiple clients) by using spawn.
- Patch: Second argument for hiIsValidClient hook: reference to the current html_interface object (used by crew monitoring computer).
- Feature: procqueue singleton. You can use this to put proc executions on a queue. Used by the crew monitoring computer to queue the update "for the next tick" when humans move.
