this commit contains the reimplementation of the scoping. The complete scoping is removed from the ACG. Additionally some code from the ACG is transfered in a Helper that manges labels, scopes and variable creation in a stack. All checks from JSRVariableScopeCodeVisitor are transfered into the ClassCompletion verifier or the new VariableScopeVisitor. Additionally some checks for labels were added with the LabelVerifier. ACG was changed so a DeclarationExpression will no longer create a local variable and if a variable is a filed or protperty accessed from inside a closure ACG will no longer try to access that field directly. Instead the closure has to resolve these cases at runtime.
Note: this commit should pass the tests but is imcomplete due to missing tests.

this committ removes the class org.codehaus.groovy.ast.Type completely and transferes its functuanality to ClassNode and ClassHelper. A ClassNode can now be a primitive type or any other type created with an class file available. ClassNodes can now be primary, which means they are the a result of a class definiton in a file - unlike a ClassNode created from a Class. All phases till actual class creation should work on ClassNode instead of Class. So all Class handling code in ACG is transformed to ahndle ClassNode instead. A ClassNode can contain a redirect now. This is used when multiple names point to the same ClassNode. This mechanism was used instead of a replacing like with the Type class. This was needed because all class resolving code is transfered into a single phase right after creation of the groovy ast and to avoid creation of huge amounts of code to replace a ClassNode in statements and expressions.
The Compiler is now able to enqueue source files. This means when ever a compiler phase found out it is necessary to compile another source file it can put this file into the compiler using the addSource method of CompilationUnit and leave the rest to the compiler. The compiler will then go back to the initialization phase and proceed to the goal phase ignoring all already handled files but the new added file.

This patch removes many string descriptons of types from the class generator and enfocres the usage of the class Type instead. A new interface is introduced for nodes which are possible variables

added code for static method dispatching. The main changes are in AsmClassGenerator2, which deprecates AsmClssGenerator, and all the Expression subclasses and nodes that deal with type information. Some changes are not really related to call dispatching, but I have included them in the batch. The early-binding mode is turned off by default (see AsmClassGenerator2, line 200) the default mode checks for -Dstatic.dispatching=true and turns on early-binding accordingly.
