added check for available connection

rclone_script-install.sh
* added new configuration setting for needed connection
* changed the way commands are added to other files (from ECHO to PRINTF)

rclone_script.sh
* added new function getAvailableConnection
* changed both downloadSaves and uploadSaves so they react on that new function (check if the available connection is greater than the needed connection, else error)

rclone_script-menu.sh
* added new menu item to re-set the needed connection
