ui:tabs breaks when tab links contain dot

Same problem that #2715, but developer only ​fixed problems with ':', not with '.'. Period also needs to be escaped in CSS selectors.

Suggestion:

        _sanitizeSelector: function( hash ) {
                // we need this because an id may contain a ":"
-               return hash.replace( /:/g, "\\:" );
+               return hash.replace( /:/g, "\\:" ).replace( /\./g, "\\\." );
        },
 
        _cookie: function() {
