Updated version message for compiler to 1.8.13

Added poor mans version of new version processing in latest 1.9 RC2, this
version will just fall back to 1.5 instead of 1.4 when it gets confused
(so it will tolerate Java 10 a little more).

Debug message added for problems found when parameterizing a type
and there is a mismatch in number of expected type variables (which
can occur when you haven't fully updated your dependencies across
your project). This debug info should at least tell you the type
involved rather than a generic message about their being an issue.

Compile error: ClassCastException thrown: org.aspectj.weaver.MissingResolvedTypeWithKnownSignature cannot be cast to ReferenceType

Multiple changes here:
- annotation unpacking is smarter and if it only needs runtime
  retention annotations it uses reflection and doesn't unpack the
  bytes to discover class level retention annotations.
- Reflection worlds are shared if for the same classloader.

New Xset option generateNewLocalVariableTables defaults to true
but can be set to false. In some situations incoming bytecode
for weaving doesn't want them adding (e.g. android situations
where the bytecode is a bit funky).

1.8.6 release prep
1.8.6 pom updates
Fix rogue chars in javadoc
rebuilt with javadoc fixes

Modified test expectation system so it is possible to say
the test cares about one particular message and the rest
do not matter (prefix message string with '*') - crude but
quick.

Polished many places to exploit generics

Upgraded all the tests to work on Java8 - some serious changes
regarding ajdoc on Java8. Hopefully it has stayed backwards
compatible with earlier JDK versions (e.g. if using AspectJ 1.8.3+
with a JDK less than 8) but no explicit testing done for this.
