Title: State serialization and tron daemon

Resolves #140, #119, #113, #112, #111

* Support multiple options for state serialization (sqlalchemy, mongo, shelve, yaml). State serialization no longer forks. Code is under `tron.serialize.runstate`
* trond now uses python-daemonize and supports a graceful shutdown (SIGINT)
* cleaned up the api

I'm not sure if this should be 0.4.2 or 0.5.
