* Configurable time until sieged claim is resecured
Fixes#113.
Makes the five minute period after winning a siege, during which the claim is
not secured, customizable.
* Make trapped words fully configurable.
Before, it contained hardcoded checks; the value of
`Messages.TrappedChatKeyword` was in addition to the hardcoded ones.
Make it more flexible, so you can override them entirely (and provide as many as
you want, comma-separated), and an empty value disables the message totally.
(Default value is 'trapped;stuck' to provide the same behaviour the hardcoded
checks did.)
Show the claim size to those with griefprevention.seeclaimsize when right-clicking with the investigation tool
(stick by default) - it's not exactly private information, the claim boundaries
are visualised so it would be easy to just count the blocks or compare the
coords of the corners to find out.
