Auto-Rewind Wall-Mounted Drybox bottom without silica compartment

This was addition to make the perfect wall-mounted drybox solution to use with MMU2S. I got it working nicely, but I can't say the same about MMU2S. So I decided to remove MMU completely. 

As my solution was combined from a lot of remixes, I'll list them all:
