[patches] rename dev to DEVICE in freifunk-policyrouting hotplug script

This should fix #46 and add the policy once the device is up.
The dev variable was empty. Netifd provides a DEVICE variable to
hotplug/handler scripts.

[patches] remove call to network_get_physdev

The device is provided by netifd as DEVICE so the call to network_get_physdev is
redundant.
[patches] fix freifunk-policyrouting

At the moment netifd can not create ip rules for wirless interfaces or only some
rules. This is due to the async nature of wireless interfaces and how netifd
initializes these interfaces.

This change makes sure that the unreachable rule is created even if there is
already a rule for the olsr-default table lookup. The unreachable rule does need
a condition on its own and should not be coverd by the olsr-default table lookup
condition in the if statement.
[patches] create lookup rules in hotplug olsr script only if smartgw is disabled

The smart gateway extension of olsr creates lookup rules. We do not have to
create the lookup rules in the hotplug script otherwise we have duplicated rules.

It's important that the olsrd default setups a properly configured e.g.
RtTableOlsrPriority.
[patches] remove 003-comgt-dep-ppp.patch

This should be fixed upstream and we do not plan to support exotic setups with
3G/GPRS hardware.
[patches] policyrouting - add rules for smartgateway tunnel

The check if SmartGateway was enabled is redundant because we grep if the
rule was there already. To get SmartGateway working olsr-tunnel rules must be
added added before olsr-default rules.
[feeds] update luci - add priorities for RtTable parameters in profile_berlin
[patches] added RtTable and SGW parameters to profile_berlin
