Title: Aria role search instead of form

Currently search forms have a role="form" and the input boxes have a role="search".

The specs (http://www.w3.org/TR/wai-aria/roles#search) state:
> search (role)
> A landmark region that contains a collection of items and objects that, as a whole, combine to create a search facility

And (http://www.w3.org/TR/wai-aria/roles#form):
> form (role)
> ...
> For search facilities, authors SHOULD use the search role and not the generic form role.

Therefore we should drop the role="form" and move the role="search" to the form element on search related forms
