We have enough gray recipes, but brown is more difficult.

Fixes #1710

Create a simple triplet table (src1, src2, dst) for all the dye
recipes and group them logically, with a bit of explanation where
they actually come from.

This prunes a lot of recipes from the list, but the old list had a
ton of combinations that did not make any sense, as well as recipes
that were just gross approximations and duplicates, mixing the same
color with itself just to get the same color back, which just wastes
packets at logon.

The list has been checked to allow all colors created from the basic
dyes (flowers+coal) so that all colors can be crafted.

Correct 2 inconsistent mixes
Clean up code style and vertically align mix table
Remove dyelocal and simplify table names
