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

 ### GENERAL
-    * should be using jsonify to return real json to my API calls, e.g:   
-        use make_response( jsonify (... ) )
-        -- [TODO] all POSTs should follow new status behaviour (unless its a form POST, as that immediately renders the form in flask and will show the Status)
-           all GETs stay as is for now (as they expect a html reply, not data, and then html is base.html+ and it handles the status)
-        -- [TODO] find persons needs an array returned - test this, also viewlist
-
     * delete files should behave like /move_files (stay on same page) as well as the status messages above
 
     * all routes should be consistent naming conventions (with or without _ )
