Sets up the theater holodeck, minus the map changes

The theater holodeck is smaller and has limited uses, but it has more programs.  These programs are simple set pieces, as befits the theater.

There are now also multiple types of holographic glass because I didn't want to use theirs.
Migrate back to tgstation as the map base.

Standard Sayustation map changes, plus additional changes below:
Adds the theater holodeck.
Adds the emergency medical program to the main holodeck.
Adds a public garden by arrivals.
