Full colour table borders in .doc export

Currently LO writes table cell border information to .doc files as part
of the "sprmTDefTable" property, but this only supports the WW8 (Word '97)
BRC (BoRder Control) structure which can only select from 16 colours.
There is no newer version of this property.

This commit adds output of an alternate property "sprmTSetBrc" which
specifies border details for a sequence of cells.  There is a WW9
(Word 2000) version of this property supporting full colours.

For LO I have used the constant name NS_sprm::LN_TSetBorder following
the existing naming convention here, which is to use *Border for the WW9
version because *Brc is taken for the WW8 version.
