[Cocoa-sharp] Cocoa namespace

[Andrew Brehm]

If it's not too late...

Could Cocoa classes revert to their NS... names in the Cocoa namespace
in future versions of CocoaSharp?

I am thinking Cocoa.NSTextField rather than Cocoa.TextField.

That would make documentation easier and also allow better
differentiation from other .NET classes in other namespaces. It's not
a problem for NSTextField, but I think it could be confusing for
NSString and .NET's native String class.
