Added a recolourable flannel jacket. I have managed to make the whites light enough to show any colour whilst keeping the gradiants and the blacks.
It is a separate option to the other recolourable jackets, as I couldn't figure out the way to add it as a weak to the list without making the others recolourable too. I think that's just a limitation of the loadout system, as all other recolourable things seem to work the same way.
