Courier's helpers mk1

[courierbravo]

Adds 4 maps located in the helpers folder to aid map design. Each map is intended to have content added, and to be scaled as needed. Each map is also themed, lumping various things together. Also, reorganizes the helpers folder, creating two new folders. Guidelines contains the three previous maps in the helpers folder. Prefabricated holds the previously mentioned 4 maps.

don't put multiple trash pile structures on one turf - it's going to look very bad visually and definitely not on top of these dumpsters

missing other side of the door on all of these

Requested changes were made. The trash piles were replaced with 3 "junk" random trash spawners per bin. Double doors fixed. 23 instances of density/pixel shifted venders have been corrected, some rooms modified to accommodate changes.
