Small and last update

• rewritten major part of UI code, mostly eliminating any possibilities for softlock
• changed placement of items
• shortened some item descriptions
• made backtracking more fun ;)

It isn't a lot, and the project most likely will be put on permanent halt.  I had some ideas, but realized these just wouldn't work in a 2D sidescroller, or would take it in the whole other direction in terms of tone or atmosphere. This is the last update.
