- Make network-manager package get installed when accessing the index page of
networks. Also freedombox-setup shold actually pull network-manager package
as dependency and use it for configuring the initial networks.
- Remove the /connect page and re-use the /add_wifi page for that purpose.
- Fix add connection page titles.
- Handle the case when network-manager returned empty string for SSID.
- Don't explictly URL encode the Wi-Fi SSID when adding a new Wi-Fi network.
Django automatically handles this in 'url' tag and decodes before url
routing. Relax the regex that matches SSID as part of the URL to handle all
possible SSIDs.
