More changes to SCP-173

- You can now manually set SCP-173's scare and neck snap sounds. Clears
up code a bit and allows more advanced gimmicks
- Clarified a few comments
- Snap damage now rand(120,150)
- Admin message now allows jumping to victims. You can use aghost to
follow SCP-173 otherwise
- Darkness check should be fixed (No longer includes unsimulated tiles
erronously, which sadly included tiles like the asteroid and maybe the
shuttle)
Changes to Meteor

- All times are now set in advance. Admins are also made aware of these
times 45 seconds into the round
- Space Weather announcement has 70 % chance of being off by up to 1
minute 30, and 30 % chance of being off by up to 4 minutes
- Shield Gen changed to Shield Projector. Allows to defend space 2 tiles
around it in all directions. Can be deployed in hallways to defend
sudden breaches or in Bar Maint to defend holodeck. Your choice
- Normal RCDs no longer shorted out. Borg RCDs are for now though since
they have far too much ammo available constantly and allow wall-ins
