Slight rewording of 2.4 success criteria

Here is a proposed simplification of the success criteria for  2.4

Present wording:
	1. 	Any authoring tool that provides Web  content (e.g. 
templates, clip art, example pages, etc.) that is bundled with the 
authoring tool or preferentially licensed  (i.e. provided for free or 
sold at a discount) to the users of  the authoring tool (as compared 
to non-users of that tool), then  all of that Web content must @@BF: 
, when inserted/added,@@  always conform  to WCAG.

Proposed new wording:

Any Web content that is bundled with the authoring tool or 
preferentially licensed to the users of the authoring tool (i.e. 
provided for free or sold at a discount), must conform to WCAG.
