Add annotations to AST

Annotations are added to UiObjectMember.
This makes it easy to find the annotations of any UiObjectMember
through the annotations attribute.

The clean AST approach would add an UiAnnotatedObjectMember that contains
both the annotation list and an UiObjectMember, but that makes
finding the annotation more difficult.

The annotations are not visited by default, if one wants to dump them
before the current object the simplest way is to use the preVisit and
use .uiObjectMemberCast().
Depending on how we use annotation we could change the current
approach.
