.d.ts type generation doesn't respect the include filter parameters on a per-type (enum/class/struct etc.) basis

[nichamp]

For example, if one were to pass -include Windows.Web.Http.HttpStatusCode to jswinrt, the native codegen correctly emits only HttpStatusCode in that namespace, whereas the .d.ts output includes all the other types like HttpStringContent. These should ideally align so that the developer writing TS doesn't accidentally use an-unprojected API.
