The way in which this is ordered seems like it will somewhat block the
ONE TWO and THREE keys for editmode (making the EDIT_GPENCIL assignment
more or less redundant btw. -- and SCULPT wasnt working).

The remaining FIVE, SIX SEVEN are now used for sculpt, vertexpaint
(added in this patch), weightpaint (bringing shortcuts in line with
meshes) and moves drawing to EIGHT.
