It should not affect the AST generation nor API.
The Core Model has a number of inconsistencies, IStruture is one.

1) Declaration of structure foo:
	struct foo;

2) Definition && declaration of structure foo
	Struct foo {
		int bar;
	};

3) Definition/declaration of structure foo, declaration/definition of variable foobar
	Struct foo {
		int bar;
	} foobar;


In the model, now for 1, 2 everything is an IStructure.

Modules lile OpenType view, Class hierachy view, C++ browsing perpspective need
to see distinction in IStructure.

So for (2)
  IStructureDefinition extends IStructureDeclaration, IMember {
  }


The IStructure we have now is actually an IStructureDeclaration, rename
IStructureDeclartion should minimize the confusion.
