Support for multiple libraries

[gregsdennis]

I think it'd be cool if this site could be set up with a lib selector which would allow testing the same schema with different libraries.

I'd be happy to set up a server that could be called to perform validations using JsonSchema.Net.

It would need a disclaimer that says client-side validation isn't supported for this and probably other libs.

Alternative to calling a server (for .Net at least)
