Many changes:

  - Split off the actual agent work into a separate src package in preparation for creating separate jars. Involved a lot of renaming
  - Renamed TransformCompilationUnitDeclaration to TransformEclipseAST, as this class will also be transforming e.g. MethodDeclaration objects.
  - Expanded the patching to also patch in transform calls when the parser fills in the Statement array for existing constructors, methods, and initializers.
  - Redesigned the ClassLoaderWorkaround class quite a bit.
  - Positioning should not work correctly ('jump to method' should jump to the getter annotation).
(Apparently, Clinit objects are always fully parsed in the original run, so no need to patch anything there).

+ * 
+ * Note that, for any Method body, if Bit24 is set, the eclipse parser has been patched to never attempt to
+ * (re)parse it. You should set Bit24 on any MethodDeclaration object you inject into the AST:
