New !COLOUR finish

[Travis Cobbs]

Here's the draft:
https://www.ldraw.org/fabric-draft.html

You asked us to proofread the draft. Just to check, all you did is add the following two lines, correct?

FABRIC [VELVET | CANVAS | STRING | FUR]

and

FABRIC is used to specify a surface finish for fabric. Omitting the second qualfier assumes a finish similar to the fabric used in Minifig capes.

Assuming this is correct, I did proof these before calling for votes, but I somehow missed the misspelling of "qualifier" as "qualfier". Everything else looks fine, though.
