Second 'soak' release of the ClassHierarchy branch.

This release should not yet be considered 'stable', but it should be quite usable. Please file bugs to this repository.

• Resolve 'convenience' imports that do not export a class named similarly to the file. (TiVo Issue #55)
• Update unbalanced preprocessor token highlighting and detection.
• Improve indentation of comments and preprocessor macros.
• Update for Grammar-Kit 1.2.0.1
• Fixed syntax rules (BNF) for constructors and external functions.
• Fixed syntax rules (BNF) for code blocks; removed them from being valid syntax everywhere an expression can appear.
• Fixed syntax rules (BNF) to allow meta tags on typedefs. (Tivo Issue #94)
