#12908 but by me

Added get_dimensions() proc to map elements, and get_map_dimensions(file) proc to maploader. Both of them return a list with the map file's width and height.
Added populate_area_with_vaults() proc. It randomly fills an area with multiple vaults. The vaults will not overlap with each other. The area can either be an actual area object, or a list of turfs.
Added datum/map_element/customizable/vault_spawner for testing the proc above. It fills a rectangle (from 4x4 to 400x400) with random vaults
Made vault spawning use the proc above - a lot of bad code removed, now you can change amount of spawned vaults
Incorporates #11994, raising amount of spawned vaults from 1-10 to 5-15.
