gluon-announced and gluon-announce are merged to gluon-respondd.

By not executing all scripts from gluon.announce themselves, both should
be considerably faster and lighter on RAM usage.

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.

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

This replaces announce.sh with a lua script of (hopefully) equal
functionality. Using lua generating JSON is much faster than jshn and
allows for greater flexibility.

+ mgmt and forward counters
+ packet in addition to byte counters for everything

* Merge gluon-alfred-ffmap into gluon-alfred
* Use gluon-crond instead of alfred's "facter" mechanism based on the broken busybox crond

This is the most basic core of the Gluon framework. Most upgrade scripts will
have to be rewritten and/or moved to other packages.
