Continuous work on the type provider

[Horusiath]

Current type provider is clearly proof of concept, it work only on queries, and only of flat fields structure.

Things to be done:

• Explore the possibility to generate namespace with full type definitions, not only the queries (prerequisite: Allow parser to generate type definition from GraphQL type format #7). This would actually make more sense in our case.
• Using type provider to generate statically typed queries and mutations would be useful too, but the problem is lack of type info for fields, which is not included in this case. This will require providing at least schema will all type definitions. Currently all fields are of type obj.
• Add ability to generate anonymous/nested types.
• Add ability to provide arguments and variables queries.
• Since definitions can contain description field, it may be used to generate XML doc based on it.

If needed, this issue may be split into more detailed separate ones.

For now Type Provider story is no more, as it didn't look as a feasible solution for the problem. Maybe it will be useful to return to that concept in the future. Closing this one for now.
