Structuremap instead of AutoFac

[mousse31]

Hi,
di you plan the integration of StructureMap instead of Autofac ?

@mousse31 I split out Autofac support into its own project so that it would be possible to add support for one's own DI container of choice. I personally don't have plans to support anything else, but if someone comes out with a project targeting another container I'd be happy to have the repo live under the JSONAPIdotNET organization on github.
