wizard update
it would be nice to rename steps from numbers to names:
/wizard/step/wan/
/wizard/step/timezones/
/wizard/step/dns/
put passed steps to uci:
list 'passed_steps' wan
list 'passed_steps' dns
Foris should determine where to go for the next step
It should be also nice to split wizard into two parts:
- before updater run (should be present in the default image)
- after updater run
