[Ironruby-core] FW: Code Review: G19.Final

This change might break apps that already worked with IronRuby v1.0 or v1.1. The reason might be:
- IronRuby is now using 1.9.1 standard libraries, which might depend on 1.9 features that are not yet implemented in IronRuby or are implemented incorrectly.
- the app uses 1.8 specific feature that is no longer supported in 1.9 (might be a grammar change or change in runtime behavior).

If you need a stable IronRuby build that is compatible with 1.8.6 please use IronRuby v1.0 or v1.1 released in July. IronRuby v1.1 isn't as stable as v1.0 but is still compatible with 1.8.6.

And as usual, contributions are welcome. Should you find a missing 1.9 feature don't hesitate, implement it and submit a patch!

  Comment  : 
  Implements many 1.9 features and changes:
  -	Syntax - should now be fully compatible with 1.9.2. 
  -	Semantics - many fixes, some features still not completed:
	  o	Passing optional and block parameters to blocks
	  o	Compound parameters unpacking, e.g. def foo((a, b), c); end
  -	Various small changes in libraries.
  Removes version command line switches (-1.9, -1.8). The only supported MRI version is 1.9 from now on. I've kept RubyCompatibility enum for now, but it should be removed along with all 1.8 specific features.
  Since we are still missing a lot of 1.9 features many failing tests and specs needs to be disabled for now (including Rails, Rubygems, and Rack).
