Fixed a bug with reverse mode that wasn't reversing under some circumstances

one more publish just to get the mod synced up with the online documentation and update the preview image.

Bombs were not breakable enough. Inadvertently removed the glass parts on the corners that make them fragile enough to throw like grenades.

Added documentation in README.md (see link in description for a nice, readable version of this on github) and simplied options, removing options that are deprecated.

Fixed bug - when in infuse mode and sticky mode was off, a bomb would be spawned inappropriately. Energy equation was incorrect as well.
