187cf78a7c - preparation for setting up types 
- moved Object, Type, Scope  out of AST into symboltable
  - moved universe into symboltable
  - removed dead code
- fixed dependency computation (pretty -d filename.go)
- lots of cleanups
- removed tocken channel connection between parser and scanner
  (was cute, but not really needed)
