[patches] fix #79 - invalid autogenerated olsrd config

dyn gw plugin is ipv4 only. Therefor we disable SmartGateway and dyngw
for ipv6
[patches] remove RtTableTunnel* for olsrd6

For olsrd6 SmartGateway is deactivated for this reason we do not
need an tunnel table.
[patches] redirect only if no password is set

redirect after first boot only if there has no password been set otherwise
the redirection will not work.

Use http.redirect instead of javascript so users without javascript can actually
use the wizard. Reason why this was not working was misplaced <%+header%>.
move default values for olsr and network in own packages
Merge pull request #86 from freifunk-berlin/bug/auto-generated_olsrd6_config

Bug/auto generated olsrd6 config

* new packages for default values: freifunk-berlin-network-default and freifunk-berlin-olsrd-defaults (should fix #79)
* remove RtTableTunnel* for olsrd6 (SmartGateway is deactivated and therefor we do not need these tunnels
  and with that we get rid of a deprecation warning during olsrd6 startup)
* refactoring of wizard (separate code into own files)
* add hna6 support for wizard
