add word counting html to claim
1. we will pretty much never use inline styles (style attributes).  This is a stronger rule for the platform than the deck, but even here don't want to use those without good reason.  so float:right and color:red should both go in stylesheets.  This is true of card-based HTML, too, but it's *especially* true of code-based HTML. If Vignesh wants to tweak the red color, he shouldn't have to submit a pull request; he should just edit the stylesheet.

2. in general "id" attributes should be unique across a page, but since wagn lets you edit lots of cards at once, it's quite likely that at some point there will be two of these editors open on a page.  So if possible I'd recommend using a "class" here (and taking steps to make sure you've got the right class.

3. "countID" is way too generic a name.  Wikirate is going to have a LOT of numbers.  the name should be clearer.

4. DRY.  Don't Repeat Yourself.  It looks like you basically cut and pasted the content_fieldsets code.  This potentially creates a code maintenance headache, because if that code changes, you have to change it here.  try "super args" instead.

5. The character count is for the name of the claim.  why are we sticking it in the content_fieldsets?
