Apart from replacing a patch for the former by two patches for latter,
this involved minimal adaptations of the lua scripts in the following
packages:
* gluon-announce
* gluon-announced
* gluon-mesh-batman-adv-core
* gluon-status-page
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.
