## Summary: In this commit I refactor the argument-generation logic to move most of the code out of the template and into the type-generator. This logic predates #51, and I didn't think to update it there, but I think it benefits from similar treatment, for similar reasons. Specifically, the main change is to treat variables as another struct type we can generate, rather than handling them inline as a `map[string]interface{}`. Users still pass them the same way, but instead of putting them into a `map[string]interface{}` and JSONifying that, we generate a struct and put them there. This turns out to simplify things quite a lot, because we already have a lot of code to generate types. Notably, the omitempty code goes from a dozen lines to basically two, and fixes a bug (#43) in the process, because now that we have a struct, `json.Marshal` will do our work for us! (And, once we have syntax for it (#14), we'll be able to handle field-level omitempty basically for free.) More importantly, it will simplify custom marshalers (#38, forthcoming) significantly, since we do all that logic at the containing-struct level, but will need to apply it to arguments. It does require two breaking changes: 1. For folks implementing the `graphql.Client` API (rather than just calling `NewClient`): we now pass them variables as an `interface{}` rather than a `map[string]interface{}`. For most callers, including Khan/webapp, this is basically a one-line change to the signature of their `MakeRequest`, and it should be a lot more future-proof. 2. genqlient's handling of the `omitempty` option has changed to match that of `encoding/json`, in particular it now never considers structs "empty". The difference was never intentional (I just didn't realize that behavior of `encoding/json`); arguably our behavior was more useful but I think that's outweighed by the value of consistency with `encoding/json` as well as the simpler and more correct implementation (fixing #43 is actually quite nontrivial otherwise). Once we have custom unmarshaler support (#38), users will be able to map a zero value to JSON null if they wish, which is mostly if not entirely equivalent for GraphQL's purposes.
