Mark all files as generated

[vbfox]

Each generated file should contain a header marking it as generated.

Also including the R# marker comment to ignore all warnings.

Aditionally the files might be named as xxx.Generated.cs so that R# auto-recognize them as such.

I'll also add a [GeneratedCodeAttribute] to all methods and properties generated. See : http://blogs.msdn.com/b/codeanalysis/archive/2007/04/27/correct-usage-of-the-compilergeneratedattribute-and-the-generatedcodeattribute.aspx
