Initial rough support for Scratch Shapekey

Scratch shape key types added to Key DNA. Modifications to file
reading/writing are done to save the Scratch's data.

Auto-commit property is added to the Scene's tool_settings. Versioning
code to set it to 1 by default is added.

EditMesh kernel module now has a hashing function to determine if the
mesh's topology has been changed.

editmesh_utils.c now has features to work with both the scratch shape key,
supporting scratch-based shape key recalculations, and sped-up
shapekey recalculation in case the Mesh didn't change topology.
This is draft rough buggy code yet.

UI: added Auto-Commit under the Shape Keys panel, removed Apply Shape keys
in Edit Mode - won't be needed later.

Next to do: check undo support.

Implemented draft topology x17-based hashing in BKE_editmesh

Minor cleanup in key.c

Revert "Minor cleanup in key.c"

This reverts commit 25883c59cd0320c5f0841145352aed411220def5.

Was a terrible idea after two hours of WTF crashes

Modifications to key DNA and RNA to have initial types for scratch and mix switching

It's now forbidden to set a shape key to be relative to itself

Small updates on bmesh_pe

Remove testing code from transform_conversions

Small style cleanup in key.c

A much better shapekey-movement idea

Removed place at index and updated Shape Key Move instead to do the same
thing and not break existing Python access to Shape Key move.

Proportional editing distance for BMeshes

Connected, projected and simple falloff distance calculation can now be
done from bmesh_pe.h.

Temporary terrible code alterations to test the falloff routines in transform engine

Shape keys code cleanup round 1

BKE_key_move introduced. Moves a shape key to a given index in the shape
key list. Has a wrapper operator. Can implement shape key sorting now and other stuff.
