Fix ttls template

Add a guiutils module for gui-related functions/classes that are used in multiple modules.
Replace os.access with os.path.exists
Make the static gateway entry optional.
Don't auto-connect/reconnect when the gui is open.
Fix bug that would keep the gui from working if the wired network entry was displayed.
