Minor errors

[AbergDevcore]

Nothing showing in site audit when there is only one site and console error of null when auditing blocks. In _layout on row 144 the conditional expression checks for "$tabs.length > 1" while it should be 0, and on row 183 the selector $('#tbl-content-types tr') in cludes the table header row, causing a console error. Concider using selector $('#tbl-content-types tbody tr')
