Support @Veto annotation.

Seam-solder reference guide:

2.1.1. @Veto.

Annotating a class @Veto will cause the type to be ignored, such that any definitions on the type will not be processed, including:
• the managed bean, decorator, interceptor or session bean defined by the type
• any producer methods or producer fields defined on the type
• any observer methods defined on the type

For example:
@Veto
class Utilities {
...
}
