Feature c# clients

For C# PdfWebApiClient:
- Refactors/Renames all code to conform C# best practices (checked by FxCop)
- Added/Modified ALL documentation
- Moves ConsoleTestDriver to separate project
- Converts PdfWebApiClient to library/assembly
- Moves Requests into their own directories
- Moves publicly exposed request inner enumerations to their own files in request directories
- Adds LAB color model option to RenderPages
- Adds G3 and G4 compression options to RenderPages
- RenderPages smoothing option is now a bit-flag enumeration so combinational operations can be used

Why make this lowercase? I think it's more correct to have PDF and API capitalized.
