Add 2nd tincture selection for some charges

[Blipz]

Would you accept contributions for this?

If so, what should the JSON object for a charge look like?

• {"charge":"rose","t":["gules","or","argent"],...} (possibly breaking compatibility)
• {"charge":"rose","t":"gules",otherTinctures:["or","argent"],...}
• {"charge":"rose","t":"gules-or-argent"],...}
• something else?

Yes, if it's good and well-formatted.

should the JSON object for a charge look like?

I don't know, it will be a very significant change. Something like {"charge":"rose","t":"gules","t2":"or",...}
