Temporarily ignoring GroovyScriptFactoryTests#testResourceScriptFromTag in order to allow more important fixes to roll out.

The problem was that the Messenger object was not being proxed (assertTrue(AopUtils.isAopProxy(messenger)) was returning false).  The cause for this seemed to be that the
pointcut was malformed / out of date, reading execution(* org.springframework.scripting.Messenger.*(..)), when the groovy Messenger class is actually declared in the org.springframework.scripting.groovy package.
I tried updating the fully-qualified package name in the pointcut expression, and this caused AspectJ matching errors saying that there was not such type that matches that FQ name.
So as a final resort, I removed the full-qualification entirely and went with execution(* *..Messenger.*(..)).  All tests pass now, but it raises the question, why was AJ having matching errors?  Is it because
the pointcut matching is being done before the groovy class is loaded?  There could be a potential bug here.

(temporarily) increasing visibility of the ConfigurationClassAnnotation interface in an attempt to resolve the issue encountered at http://is.gd/tCud

revised support for annotated factory methods (merged @FactoryMethod functionality into JavaConfig facility)

Fixed whitespace and added private modifiers to @Value-annotated fields in the @Configuration example

filled in some basic details on the type conversion support.  No TODOs left in this section now.  Also properly added the selection/projection sections.

changed to [] from {} for projection and selection (including first and last selection).  addresses the problem of clashes with template prefix/suffix

storing type information as specified (SPR-5556, SPR-5562); explicit XML array element in spring-beans-3.0.xsd (SPR-5543)
