Partly revert "[feeds] update feeds.conf"

This partly reverts commit 523ac00131dd43d8dc1c9262c1708a7e60af850f. We are
going to use quilt to patch the feeds repositories too. So there is no need to
fork the feed repositories.

Conflicts:
	feeds.conf
[patches] add bind ipv6 only patch for olsrd txtinfo and jsoninfo

This patch is already upstream but we are waiting for a new release
of olsr and the openwrt routing feed.
[patches] import luci-freifunk-gwcheck.patch
[Makefile] let make clean invoke ./scripts/feeds clean

fixes #13
[patches] import luci-freifunk-map.patch

This is a candidate for an upstream fix. Maybe we should use something like this
instead:

<a href="//wurstwasser.com/doener">
[patches] import luci-mod-admin-dfs.patch

Enables dfs options in the wifi mod admin interface (as far as I understand).
This should actually patched upstream.
