Also did some Refactoring for Classes that implement and use
INativeBuffer.
The memory usage reduction for rendertargets resulted in some
refactoring of the directx texture classes.
Also added DebugNames for some DirectX resources in case of a debug
build.
Fixed a performance problem in the Visual Studio extension where no importer or processor was selected for an asset.
Fixed that the asset names for Uri encoded in the build output.
Fixed that errors when serializing assets get logged.
Sped up ImporterManager.GuessImporterByFileExtension, which caused performance problems if many assemblies are loaded into the current AppDomain.
Made the AssimpImporter library deploy the binary files again (hopefully just a temporary solution until we've found a better way.)
Provide a extension for TargetPlatform enum for getting the DisplayName of an entry.
Changed that ProcessorManager.GetProcessorDisplayName doesn't throw an exception if no processor with the given name exists, which now mimicks the same behavior as in importerManager.GetImporterDisplayName.
Replaced the old VS templates with ones that offer more flexiblity.
Started replacing the Content Project for the samples with our custom project type.
Inlcuded a basic not yet working AssimpImporter.
