server side: launching script improvments: - no more difference between installed version and source version: libervia is a deamon by defaut, "fg" must be used to launch it foreground - fixed bad constants module imported in python part of libervia.sh - fixed stdout encoding in python part of libervia.sh - APP_NAME and APP_NAME_FILE use the constants module values - DATA_DIR variable moved to PLUGIN_OPTIONS - (constants) ASCII_APP_NAME renamed to APP_NAME_FILE to be consistent with SàT backend.
