    Merge back branch alg_writerframes to trunk

all of which set all RES_FLYFRMFMT and RES_FRMFMT SwFmts
to use the new fill attributes, but

a) didn't change the aTableBoxSetRange for SwTableBoxFmt to include the XFILL
attributes, so importing cell bgs from .doc got dropped
b) didn't make any effort in the uno api for XCells to do the same sort
of mapping that was done for XFrames

its unclear to me if SwDrawFrmFmt is actually adapted or not, I've
assumed that it is here
