Fixed the about_objects.rb file

Learned:

* Everything is an object
* Objects can be converted to strings
* Objects can be inspected
    This one mad me wonder if THIS is the output in IRB and not .to_s
* Every object has an ID
* Every object has a different ID
* Some system objects always have the same ID, like certain constants and small integers
* When an object is cloned, it is given a new object ID
