Andrew Nicols 0f3bbfd4f8 MDL-55982 mod_forum: Add time-based discussion locking 
This patch adds support for time-based locking of discussions.
Discussions are automatically locked after a user-definable period of
inactivity. After this time, only those with the the relevant capability
are able to add replies.

This has been designed to add support for other types of discussion locking
at a later date with relative ease.
