Title: This fixes the 'undefined' error when loading the scenarios.

Having a 'u' or 'd' wall with no 'image' set causes it to preload an image with a path of 'undefined'. We don't need those walls though! We can use 'warpPlayer'.

Also, condensed the elevator conversations and triggers into one file for each set.
