[Commotion-admin] [luci-theme-commotion] When dnsmasq fails all luci interfaces break (#16)

[Seamus Tuohy]

This issue in on line 103 of the header where the check does not check to see if it has been passed an empty ipv4-address table. An empty table like this is invalid but will occur when dnsmasq fails.

```
  uci:foreach("wireless", "wifi-iface",
                         function(s)
                                 if s and s.mode and s.mode == "adhoc" and s.network then
                                        local iface = conn:call("network.interface."..s.network, "status", {})
                                        if iface and iface["ipv4-address"] then
                                         if iface ~= nil and iface["ipv4-address"][1].address then
                                                 mesh_ip = iface["ipv4-address"][1].address
   ```
