Refactored "And" objects to a single generic object

Changed ViewResultExtensions to ViewResultBaseExtensions
Merge pull request #3 from roend83/mvc4

Refactored "And" objects to a single generic object. Some return types in ActionResultExtensions (i.e. ViewResultAnd became ActionResultAnd<ViewResult>), so it could break someone's code if they wrote extension methods based on those return types.
Updated version
Updated to allow partial versions for nuget. Updated the version to 1.5.9.1 to state that it is for v 0.5.9 of mspec.
updated to mspec 0.5.10
