bug: import/importables fail to set newid correctly. Looks like I broke import when I was fixing a scandir issue. Overindented a couple of lines. This prevented the next used id from being set properly. It also resulted in wierd output when importing (bunches of newlines). Also fixed the two export/import tests to verify the new nextid for all the classes is equal or higher than the old one. Ideally they should be equal, but there is a bug somewhere where we get a double increment in the export/import cycle dropping a number or two.
