WIP: ASTBuilder (#1358)

* Compiles.

* Small tidy up around session/ASTBuilder.

* Tests are now passing.

* Fix Visual Studio project.

* Fix using new X to use builder when protectedness of Ctor is not enough.
Substitute->substitute

* Add some missing ast nodes created outside of ASTBuilder.

* Compile time check that ASTBuilder is making an AST type.

* Moced findClasInfo and findSyntaxClass (essentially the same thing) to SharedASTBuilder from Session.
