Sunset Canyon 1.2

- Added Some Fire Hydrants to liven up the streets
- Changed the street color while you're in the heart of the city
- Changed a few of the pot holes
- Changed item positions to space them out a bit better
- Added a MUSICDEF file!

- Fixed a few linedef's that I forgot to mark as Impassible.
- Added Death pit triggers to sections that probably should have had them to begin with to prevent people getting stuck.
- Added a few more signs to make things a bit more... Lived in? I just thought it looked nice.
- Changed the Sneaker pad Flats to something.... better? Still wish we had a 32x32 boost flat. Would kill for one.
- Filled out some item clusters with more Itembox things.
