User settings JS bug believed to be fixed by 2adae04e2d962709840e213ce3ebd91000bedd10, so removing the alert
Allows specifying sellable or buyable, instead of single exchangeable

* Right now you can mine towards all "exchangeable" currencies, but this presents a problem with currencies that we want to be able to sell, but not necessarily payout in. To fix this we split the config value in two.
Adds Rubycoin to defaults
Reworks the validate_address endpoint
