Model Changes

I have had to make several changes since taking over maintenance of Datsville:

• Removed the blue university since it is an official TLG model.
• Removed the downtown church since it is an official TLG model.
• Added a rear section and wall to the yellow shopping center. (I should probably revert this since it was not the orignal author's intent.)
• Added a rear section to the movie theater. (I should probably revert this since it was not the orignal author's intent.)
• I may also remove Anders Isaksson's house since it is not built to true LEGO scale, and is artificially scaled down by half. (For now I have left it alone.)
• Switched from using road baseplates to using SNOT roads based on designs created by Mike Gallagher.
• Restored several inlined models back to their original MPD formats.
• Undid several optimizations done to models by Tore Eriksson meant to speed up model loading. (I should maybe reinstate his changes.)
• Several models used colors that are no longer considered official and are no longer supported by most modern LDraw tools:
  • Color 258, pedestrian_012_manexplorerbinoculars.ldr
  • Color 277, vehicle_028_graytractortrailer.ldr
  • Color 354, 4150p02.dat
  • Color 487, vehicle_020_redferrari.ldr
  • Color 492, vehicle_028_yellowtraincarwithblacktrailer.ldr
