Changed interface for trigger/pubsub to match each other so we
can interchange them easily.

Rewrote trigger implementation to use publish/subscribe code.

branch : octopus.add-device-mngr

Added bitfield index for publish / subscribe + some changes with
ID registration on server.

Worked on index for publish subscribe - objects3.pl now seems pretty much ok
for benchmarking.

Getset functioning again with triggers. Trying to get pubsub to work with attribute indexes.
