Major changes: removing obsolete SN1 entry, disabling incompatible SN7 and adding SN13-SN16.

As announced, this updates the supernode entries to reflect the real-world status and enables us to use the new resources.

Update to gluon 2016.1.3

1. Updates gluon to 2016.1.3
1. Updates the list of avaiable supernodes and ntp servers.
1. fastd limit is set to 2, not 1 - see [discussion](https://forum.freifunk.net/t/fastd-tunnel-anzahl-limit-2-oder-lieber-5-traffic-impact/10280/18).
1. change configmode - outputpages and also add en.po - while it is often needed as default (but not translated, its just a copy of german, could also need some supersweet formatting enhancements)
1. rebuild site.conf and add many options (which are not neccesarily active) (as needed and described the [documentation](http://gluon.readthedocs.org/en/v2016.1/user/site.html))

For additional Information about what changed in Gluon, refer to its [changelog](http://gluon.readthedocs.org/en/v2016.1.3/releases/v2016.1.3html).

Update gluon to v2016.1.3. The release notes do not mention any
specific instructions on how to upgrade. Hopefully this means
the upgrade can simply be made without any migration steps.
http://gluon.readthedocs.org/en/v2016.1.3/releases/v2016.1.3.html

Log upgrades upon completion to make it easier to find nodes where
the upgrade failed.

Migration files to migrate location and fastd can be removed as
there is no longer any experimental gluon version in the wild.

Update gluon to v2016.1.2. The release notes do not mention any
specific instructions on how to upgrade. Hopefully this means
the upgrade can simply be made without any migration steps.

Convert bandwith limit accoding to release notes:

Gluon needs its own repo for kernel modules as it uses a custom kernel.
The official OpenWRT repository seems to be down frequently. So we add
our own mirror as the source for packages.

Add sn7 to list of super nodes. sn7 currently runs batman-adv protocol
version 15 which is incompatible with the currently used version 14.
See also:
https://www.open-mesh.org/projects/batman-adv/wiki/Compatversion

Nodes connected to sn7 will not be able to mesh with Freifunk unless
they use version 15. By default two super-nodes are used when
connecting to Freifunk so this should not be a problem as long
as only one node runs protocol version 15.

Decrease MTU of fastd to 1280. This will enable clients with small
MTU to connect to fastd. This includes at least Unitymedia/KabelBW
which runs IPv4 over IPv6 and therefore has a reduced MTU using IPv4.
However this will break IPv6 in Freifunk as packets of size 1280 -
32 bytes (the latter is batman-adv's header) will get fragmented.
IPv6 requires an MTU of at least 1280. This will not be the case
with an MTU in fastd of 1280.

Updates gluon to 2016.1. Additionally update the list of avaiable
supernodes and ntp servers.

Reduce parallel connections to supernodes

Reduce the number of supernodes a node connects to. This is done in order
to reduce the amount of broadcast traffic sent to clients. Currently
a supernode sends about 3MiB/s broadcast traffic to clients. Reducing
the number of nodes will hopefully also reduce the amount of broadcast
traffic on supernodes.

de.po can only be copied into gluon if it exists, so a depency
was added.

Removing the mac address in next_hop breaks compiling gluon. Reverting
the removal fixes the issue.

Added BUILD_NUMBER and GLUON_BRANCH to instructions so users remember
specicy their own settings.

change subnet to /19 , Wireless hardware mode from n HT40+ to HT20 for better low singal performance, apply config format changes from gluon

Change limit to 4 and remove v4 on sn3

Moin

Der sn3 hat v4 und v6 somit ist keine Limitierung auf ipv4 mehr nötig

See merge request !8

Add fourth super node for even more redundancy.

We need more IP addresses so the net was extended to /19.

Added a backup key from CCCFr just in case there is no second key to sign release firmwares.

Changed the version number used to the same version as specified in
the tag of gloun checkout (without the prefix v). This is more
consistent to the versioning that has been used before.

Bumping Gluon Buildenv to v2015.1.2

Done some adjustments and fixes to use the v2015.1.2 gluon buildenv.

With this new firmware is based on Chaos Calmer (http://downloads.openwrt.org/chaos_calmer/15.05/) and should be still compatible with the old firmware.
