Refresh of DefinitelyTyped

[srunnoe]

Tomasz,

Forgive me if I got this wrong, but it appears as though the mirror of this repo under DefinitelyTyped is stale. I tried including it in my project via DefinitelyTyped and noticed that ModelFields is outdated and resulted in compile errors.

New variant....
export type ModelFields = M['__fields'];

Stale in
https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/redux-orm/Model.d.ts

Fixed in
https://github.com/tomasz-zablocki/redux-orm-types/blob/master/types/redux-orm/Model.d.ts

I spent a lot of time trying to fix it myself before realizing that you already had a fix in place. Learned a lot along the way. Writing declaration files is a tough business, thanks for all your hard work!
