adds three methods - one to retrieve the text of a i element, another to
 retrieve a i element, and another to check for it's existence.

 @example
   i(:italic, :id => 'title')
   # will generate 'italic', 'italic_element', and 'italic?' methods

 @param [Symbol] the name used for the generated methods
 @param [Hash] identifier how we find a i.
 @param optional block to be invoked when element method is called
