fixed resetting Leonardos before upload"all done" message - rewrote Importer.finish() to make the exit process more consistent - moved Doit's message definitions to Doit - ensure the importer is destroyed in Doit.onPause() - only show the toaster popup if a) there is an importer to abort, and b) the abort actually did something (i.e., it's not already aborted) - bugfix: added some checks for abortion to the Importer after wait()ing after a dialog. Importer.wake() now alsy does a notify() to break out of dialog waits. - also, made Importer.checkAbort() protected, so it can be checked from specific importers as desired
