Primitive types

[yallie]

Looks like we can't use .NET primitive types because of the missing APIs.
Examples:

• string.replace(text1, text2) → string.Replace(text1, text2)
• int.valueOf("123") → int.Parse("123")
• etc.

I suggest that we emit String, Integer and so on — the mockable types defined in Apex.dll.

There's a big gotcha: we'll need to implement all these Apex classes to use them,
while .NET primitives are already available out of the box, albeit with their own APIs.

Current approach:

• Static methods are not translated: Integer.valueOf(x) remains the same
• Instance methods are implemented as extension methods in Apex.ApexSharp.Extensions
