Bit Nudging

[Aeltumn]

I was planning on adding bit nudging to the wrench as optional modes, as these were a part of Algorithm's "Project: Blueprint" The concept of nudging is the ability to move bits around as if pushed by a piston on a small scale. However the way it was implemented in "Project: Blueprint" is, bad. Block nudging just moved the entire block like a piston and bit nudging required specific circumstances to even work. I'd make it so that the wrench acts like a miniature piston and you move 12 bits back but I'd say it'd be better to have it always push the bits back and remove any bits that would get in the way. It'd also have to push bits into neighbouring blocks which is currently not something the API is good at.

For now bit nudging has been removed completely to be re-added at some point. This issue is a location to give feedback on how important it is to add bit nudging.
