Did some minor changes: renamed gcode tab, renamed gcode file download endpoint, added some margin for gcode viewer accordion. Not sure yet what to do about the gcode viewer controls/settings, until I figure this out they'll stay where they are now ,)
Now UI and backend take data from saved metadata (if available). Metadata gets written after file upload and also on startup (for files that have not been added yet). Gcode analysis is interrupted if a printjob is started and resumed when it ends. Frontend is notified when new metadata comes available and UI triggers reload of gcode file list. Also started on implementing proper logging.
The location of the config folder has changed. OctoPrint will try to migrate the configuration from its old location (~/.printerwebui, ...) to its new one (~/.octoprint, ...). For this to work the following conditions must be met: 1) the old config folder exists and is a directory 2) the new config folder does not exist at all. The migration functionality will be in the future.
