Add stylechecking to test suite, fix style errors
Now prints `C{...}` instead of `$anon`.
The self type as given (or implied for module classes) in the source. Also defined and updated for normal types, not just ClassInfo types. Common functionality between this and baseTypeWithArgs has been pulled into RefinedType#wrapIfMember.
Check that the self type of a class conforms to the self types of its parent classes.
Used to test whether a tree has an attachment of a given key value.
The attachments label `New` nodes that are parents or annotations. These nodes will be treated specially when it comes to checking whether a class can be instantiated. Specifically, parents and Java-defined annotations are allowed to be abstract. Also: New convenience method: isAnnotation
- Abstract classes cannot be instantiated (exceptions: parent news and Java annotations) - Instantiateed class must conform to its self type.
An error message might be suppressed because it contains internal code. But if it is the first one, we should still print it. Otherwise, we risk a scenario where we see "2 errors" but none is printed.

Add checks that abstract classes are not instantiated and that self types conform.
This was much more involved than previously thought. Major work was needed to
