Committing settings

Editable values are stored either in RAM or a nonvolatile flash memory. The values
stored in the flash memory are in effect also after a reboot.
Some parameters have an edit-copy. If writing is cancelled, the values with an edit-
copy are immediately restored to the original value. The values without an edit-copy,
such as string values, are restored to the original value only after a reboot even
though the edited value is not stored in the flash memory.
