sc: filter: rtf: add method "WriteFontTable"

Browse source 
Write the font table while visiting column/row and
get the unique index to reference it.

"The \fonttbl control word introduces the font table group.
Unique \fN control words define each font available in the document,
and are used to reference that font throughout the document."
