Shuffling classes around.

Old Man Reflection is coming home and he's not going to like finding
out a bunch of beans have moved into his reflecting room. We had better
evict those guys before he blows his stack.

  scala.reflect.*Bean* --> scala.beans.*

scala.beans, that's kind of a fancy package name for some beans. I
figure it's time to start fishing or cutting bait on this kind of thing.
I don't even know what beans are, but if we're going to have them in the
mainline, the least surprising place to find them is scala.beans. If we
don't want to put them in scala.beans for whatever reason, then I say
they don't belong in trunk at all.

Bonus round:

  scala.annotation.target --> scala.beans.meta

I don't know if there is any more unfortunate name for a package
possible than "target". Maybe ".svn" or ".git" if you could have dots
in package names. Package CVS wouldn't hit too hard these days. Package
lib_managed? I'll try to come up with something. In any case this golden
opportunity could not be squandered.

There is a new starr included, because GenJVM contains all kinds of
shooting-from-the-hip Bean-related name hardcoding. (Yes, still. I ran
out of stones. So a few birds escape with their lives... this time.)

-/**
- * When defining a field, the Scala compiler creates up to four accessors
- * for it: a getter, a setter, and if the field is annotated with
- * `@BeanProperty`, a bean getter and a bean setter.
- *
- * For instance in the following class definition
- *
- * {{{
- * class C(@myAnnot @BeanProperty var c: Int)
- * }}}
- *
- * there are six entities which can carry the annotation `@myAnnot`: the
- * constructor parameter, the generated field and the four accessors.
- *
- * By default, annotations on (`val`-, `var`- or plain) constructor parameters
- * end up on the parameter, not on any other entity. Annotations on fields
- * by default only end up on the field.
- *
- * The meta-annotations in package `scala.annotation.target` are used
- * to control where annotations on fields and class parameters are copied.
- * This is done by annotating either the annotation type or the annotation
- * class with one or several of the meta-annotations in this package.
- *
- * ==Annotating the annotation type==
- *
- * The target meta-annotations can be put on the annotation type when
- * instantiating the annotation. In the following example, the annotation
- * `@Id` will be added only to the bean getter `getX`.
- *
- * {{{
- * import javax.persistence.Id
- * class A {
- *   @(Id @beanGetter) @BeanProperty val x = 0
- * }
- * }}}
- *
- * In order to annotate the field as well, the meta-annotation `@field`
- * would need to be added.
- *
- * The syntax can be improved using a type alias:
- *
- * {{{
- * object ScalaJPA {
- *   type Id = javax.persistence.Id @beanGetter
- * }
- * import ScalaJPA.Id
- * class A {
- *   @Id @BeanProperty val x = 0
- * }
- * }}}
- *
- * ==Annotating the annotation class==
- *
- * For annotations defined in Scala, a default target can be specified
- * in the annotation class itself, for example
- *
- * {{{
- * @getter
- * class myAnnotation extends Annotation
- * }}}
- *
- * This only changes the default target for the annotation `myAnnotation`.
- * When instantiating the annotation, the target can still be specified
- * as described in the last section.
