gluon-announce: detach announce.d from alfred

All announce.d scripts have been moved to /lib/gluon/announce/announce.d
The script /lib/gluon/announce/announce.lua will collect all information
and output json.

gluon-ath9k-workaround: Workaround for the ath9k wifi bug.

If the `monitor` attribute in the site.conf is defined, the cron
script is modifed to send debug informations, generated on bug
detection, to given remote host and port,
e.g.: "fda1:384a:74de:4242::2 8090"

Cron script which restarts wifi iff queues are marked stopped.
This script also outputs some debug information to nail
down the problem.

gluon-config-mode retains the luci frontend, all setup scripts and config is
moved to the new package.

Closes #31

The bandwidth limit input fields were missing a unit confusing users as to which value should be entered. It's kbit/s for both.

The whole status page should be rewritten ASAP, but this fix will at least
make it work again for now...

Otherwise, the state match doesn't work, not allowing replies to outgoing
packets to get in.

This also fixes the type of a few fields which were strings instead of numbers.

Original patch by Daniel Ehlers <danielehlers@mindeye.net>

For security reasons we should not accept incoming packets per default
and instead allow specific services on specific interfaces.
