Comment :  
(MiscFixes.2)

Fixes bugs:

- Protocols.IsEqual should compare references first before calling ==  
method.
- Exception#initialize should reset backtrace to nil.
- Exception#exception should not be special-cased for argument ==  
self (filed Ruby bug [http://redmine.ruby-lang.org/issues/show/1248](http://redmine.ruby-lang.org/issues/show/1248))
- Fixnum#\<\< handled overflow incorrectly.
- System::String inspect uses single quotes instead of double quotes  
to differentiate from Ruby string.
- Fixes L conversion in Array#unpack.

Adds RubyMetaObject and RubyMetaObject to handle functionality  
common for Ruby meta-objects and derives Proc.Meta and Method.Meta from  
RMO (more refactoring will follow).  
Implements a conversion from Proc/Method to an arbitrary delegate.  
Slightly refactors meta-object builder. More changes will follow.
