[MAP] Additional job closets

After a discussion on coderbus, I've got around to adding additional job closets to most departments. It turns out most departments lack enough personnel lockers for every person working there.

The basic rule of thumb is the addition of enough closets for the maximum amount of people working in that department + one more person, barring Science due to mapping constraints.

The new locker count is...

Engineering: 6 from 2
Cargo: 4 from 2
Medical: 6 from 2
Science: 5 from 2

Security is exempt as they have enough lockers for every Officer.
