RubyToC 1.0.0 Beta 5

RubyToC is a subset of the metaruby project, which aims at rewriting Rubys internals in Ruby.
RubyToC is the translation module and it is capable of automatically translating a method into the equivalent C code for a subset of Ruby.

Enhancements
- Split RubyToC to RubyToRubyC and RubyToAnsiC.
- Extended Environment to be more flexible for various situations.
- Removed propaganda (bloat) from release.
- Gemified and reorganized things. Support still needs splitting up.
- Flipped a lot of internal naming to use Unique.
- Added ruby_to_c_show (like parse_tree_show).
- Use ivars instead of cvars so inheritance wont bugger the translator.
- Corrected unsupported node lists in pipeline.
- Fixed bugs for splat args, iters, optional args, method name map.
- Fixed many other bugs.
