another large clean up of code, all POSTs are now using make_response() and returning json OR are for a form that flask handles with rendering direct html. Where there is a POST with json response, the jscript now calls CheckForJobs() to show it in the F/E. Removed several debugs. Fixed up undocumented BUG where import datetime was wrong, and prefix/suffix also to offer directories near the date of an image. Removed unused routes for clearing messages
