Use my API key to check if I know the recipe about gw2-arbitrage HOT 1 CLOSED

Some issues I've run into w/a first step implementation.

The API appears to not list automatically unlocked recipes; so we'll have to check for available chars of an appropriate crafting level as well. The API does list if a recipe is an auto unlock, at what level, for what disciplines, so there's that at least.

I've run into situations where I bought a recipe to craft something, only to learn that I needed an inscription recipe as well; so we need to check all recursive recipes.

I am uncertain how recipe data should be shown in the large table view; we have the data, so we may as well show it to influence higher level decisions.

This would be a useful precursor to #8.
