TG: - Added instructions on how to use the pretty markup to the changelog

- Added a few red corner floor pieces to security
- Added a Del() proc to blackbox recorders which makes it so a new blackbox
recorder gets made when the one is deleted and all the data is copied over, so
no data is lost. Same applies when the new one gets deleted. The new blackbox is
spawned on z-level 2, so at centcom on the coordinates X,Y,Z = 1,1,2
