MO19 General Fixes

Fixes sec and RD lockers being all access and having extra contents, I thought I had changed those to being secure lockers... Oh well.

Changes areas to have actual names so you can easily teleport to them now instead of them all being labeled as "space".

Removes shotgun shells as the runtime fix for them earlier was to just make them regular functional shells that could be fired, it turns out you can't have pre-fired shots in the map maker. I'll have to ask someone about that so we can have extra fun.
