Description

Improve creation dict typings for create factory functions. This is currently set to any but we could create a dictionary of available properties with [Distributive conditional types](http://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-8.html#distributive-conditional-types)

    These definitions from [typescript-alloy-app](https://github.com/appcelerator/titanium-boilerplates/blob/master/templates/typescript-alloy-app/app/globals.d.ts) could be moved to the main @types/titanium 
       type NonFunctionPropertyNames<T> = { [K in keyof T]: T[K] extends Function ? never : K }[keyof T];
   type NonFunctionProperties<T> = Pick<T, NonFunctionPropertyNames<T>>;
   type Dictionary<T> = Partial<NonFunctionProperties<T>>;
    -Or shorter version:- -type Dictionary = Partial>>- I was wrong, short version is incorrect.
