  * added note about String+ and Foo.class to implementation notes section

 * changed "Implementation Limitations" to "Implementation Notes" inside ProgGuide
 * added section on bytecode limitations, headed by handler issues.

  * changed "aspect aspect" to "abstract aspect"

  * manually applied excellent doc patch contributed by Nick Brett

 * fix to semantics document to describe correct semantics
 * checkin of failing coverage test case for correct semantics

  Bugzilla Bug 35551: "declare soft" in abstract aspect have no effect
Specifying that declare soft behaves like advice in that
it must be concretized to have an effect.

finally totally and completely stomped out "introduction"
minor formatting changes
generating better filenames for the progguide
added A4 version of quick reference

removed useless biblio and glossary
made a few docbook rationalizations
