Add json gem for ruby 1.8, 1.8 does not have native json.
fixes #386 - child() supports :object_root => false to suppress root node for child collection. Added tests for both root and non-root cases.
Add symbol conditionals

Now you can give symbols as conditions for :if and :unless, which are
used as method names for the object in question.

Example:

   collection @posts
   attribute :coolness, if: :cool?

Here Post#cool? would be invoked when resolving the condition, to
determine whether to include the :coolness attribute or not.
