Add DNA/RNA/BKE infrastructure for dynamic-topology sculpt mode

* Add a detail_size field to the Sculpt struct, two new sculpt flags,
  and a Mesh flag for dynamic-topology mode; that's it for file-level
  changes needed by dynamic topology

* Add RNA for the new DNA field and flags

* Add a new icon for dynamic-topology created by Julio Iglesias. TODO:
  update the icon for the new SVG icon format

* Add a SculptSession function for converting from BMesh to Mesh,
  handles reordering mesh elements and setting face shading
