Added JavaMethodAnalyzer to gather statistics about Java method. Useful for tools.

Introducion a JavaSourceDocument. JavaSourceDocument aims to keep various information abou Java source such as parse tree, index, highlighted source. A limited cache of source documents is also maintained to speed up browsing.

Comment and formatting fixes (Marcel doesn't seem to bother much with it :-)

Added bit of a comment to JavaByteCodeProcessor and JavaByteCodeProcessorAdapter

Fix in GroovyEvaluator: import all used classes when evaluating for inspector of debugger. This makes all classes accessed without fully qualified name (vast majority of code) accessible by the evaluator as well. Otherwise, Groovy won't be able to resolve classes used in the code.

Bugfix in GroovyShell - import each class/package only once. Otherwise import customizer's list of imports grow larger and larger (doubles each time a code is evaluated).

class: JavaToolbox changed: #searchForImplementorsOf:class:in:whenFoundDo: Fix for implementor searching.

class: JavaSourceHighlighter changed: #format:kind:in:

Fix in JavaMethodAnalyzer>>readGlobals. Fetches used globals from NEW, ANEWARRAY, MULTIANEWARRAY, GETSTATIC, PUTSTATIC insns. With that fix, 'spawn buffer on references' works.

subprojects (accidently added) removed....
