Supporting not_nil? in rails

Ever need to do !object.nil? - I do and frequently. This patch is
basically rolling up an extension i end up adding to every project i
work on.

Sure using !object.nil? to see if an instance is not nil works but how
much more meaningful and elegant is object.not_nil? ? Creating a
separate plugin for this small but powerful feature would be crazy so
heres the patch to better all the rails projects out there.

This patch extends Object and NilClass respectively:
"any object".not_nil? #=> true
Object.new.not_nil? #=> true
Object.not_nil? #=> true
nil.not_nil? #=> false

Tests included! Please add +1 to the ticket if your inclined to do
so...

Um... why not just do

if object ....

Should be the same as !object.nil?, right?

If readability is the objective here you can just as easily do:

"if not object.nil?" or "unless object.nil?"

Hi --

"if object" works but its a trivial example. in more complex scenarios
like:

if you_are_happy? && object a&& object.is_feeling_funky?
  object.do_something
end

Sure it works...but it loses its meaning. The less mental translation
i need to make the better...code should be easy to read. the implicit
behavior of "if object" in many contexts is not sufficient.
