Some good progress today, despite being sick.

1. Added safety code that causes chains to detach from the mending plate when it is removed from the new collar.
2. All the tools will leave “lock mode” when attached/detached/rezzed and after 30 minutes.
3. Moved a bunch of code around to save memory, as usual.
4. Fixed a bug in the timelock system (I just wrote it god dammit!)
5. Added a bolt sealing function! It’s a bit like timelocks but for bolts (with a few differences).
