Twenty Thirteen: remove searchform.php template once core search form accepts HTML5 argument

[lancewillett]

See #15081 for the core change.

Once that lands in 3.6 we can remove searchform.php from the theme, and adjust any CSS selectors accordingly.

Thanks for the patch -- can you break out twentythirteen_navbar_searchform() into a new ticket / patch please?

It's separate from the task here.

Updated. Not sure we even need to append it through a filter. Would be easier to remove for child themes though.

Changing the search form format to a filter, see #23850.

Could we add the callback in functions.php above the customizer code for code flow reasons?
