tinymce library updated to 4.0.28 (tested with ie8,9,11), fixes to filepicker due to reserved words causing errors in old browser, disabled jquery touchpunch in filepicker (not needed there as jQuery UI isn't loaded either)
updating jQuery to 1.11.1 (fixes issues with .val(), load()...), adding check for console in cms_admin (preventing errors in browser like ie8 where console is not defined, console.debug in cms_dirtyform was causing errors)
minor ie8 fix
fixing icon font issue in filepicker for ie8
missing double quote
