No-ajax search should 'return' not 'return false' [Has-patch]

[rvenable]

In global.js:

j('div.dir-search').click( function(event) {
		if ( j(this).hasClass('no-ajax') )
			return false;

Return false doesn't allow the search to function as normal even though it has the no-ajax class. I think just a simple return would be better.

The other no-ajax checks just do a simple return, so they work fine
