Sculpt: sculpt colors fixes

* Paint brush now uses its own temp attribute
layers instead of hijacking MSculptVert->origcolor.
* The various SCULPT_UNDO_XXX enums are now bit flags.
* Fixed anchored/drag drop mode for the paint brushes.
* Color hardening brush now works with dyntopo.
* Added a CD_FLAG_ELEM_NOINTERP flag to the customdata
API. If set it will either copy the first element
in the sources list if CD_FLAG_ELEM_NOCOPY is unset,
or nothing at all if it is.

This necassary to properly support the design
pattern whereby helper custom attributes
reset themselves in each brush stroke by comparing
a per-vertex stroke id with ss->stroke_id, thus obviating
the need to walk the entire mesh at every stroke start.
