Currently, the formatter in taBind will hard cut off list elements at the 4th character. This means that a class or style attribute can by typed and saved, but when the data is reloaded/bound any attributes are cut off and broken HTML is displayed.

This can be reproduced in the taBind.$formatters.spec.js tests for indenting lists.

Adding the following test to the current master branch will reproduce the failure:

        it('handle lists with attributes', function(){
            $rootScope.html = '<ul style="font-size: 10pt;"><li>Test Line 1</li><li>Test Line 2</li><li>Test Line 3</li></ul>';
            $rootScope.$digest();
            expect(element.val()).toBe('<ul style="font-size: 10pt;">\n\t<li>Test Line 1</li>\n\t<li>Test Line 2</li>\n\t<li>Test Line 3</li>\n</ul>');
        });

The test above and a fix are included in this PR. Thank you!
