Wizard for creating an AnnotationLiteral

We are recommending to developers, particularly extension designers, that they create an AnnotationLiteral for every qualifier in their public API. Creating an AnnotationLiteral can be a tad tedious. Thus, we should introduce a wizard to create them in JBT.

Here's a whole bunch of annotation literals to use as a reference:

The real time saver is creating an AnnotationLiteral for an Annotation (qualifier) that has attributes.
