New object inspector added to visualruby

Hi:

I just added an object inspector for visualruby. Its really cool. You
just have to type:

oinspect obj

Where object is any ruby object, and it will show all the public methods
and instance variables etc. When you click on a variable, it will
inspect its object in a new window etc. etc.

It takes the nspect method to a new level:

Best,
