data: storing type modifiers in edges

- ASTVisitor uses DataType instead of string to pass on type information.
- Edges can have EdgeComponents.
- EdgeComponentDataType stores information that modifies the type a ...TYPE_OF edge points to.
- EdgeComponentDataType can create a complete DataType using it's internal information.
- Fixed a bug where DataTypeModifiers did not apply their qualifiers.
