Split up codebase into the packages @clsterio/lib, @clusterio/master,
@clusterio/slave, and @clusterio/ctl using lerna to manage them. This
will allow deployment to use only the parts needed reducing install
size, and better separate the code into shared library, master, slave
and control.
Implement notification to plugins for disconnect request, connect, drop,
and close. This allows plugins to properly handle slaves and the master
server shutting down without sending messages that will get lost.
Fix research_sync sending out contribution events for the previous level
of a researched technology and sending finished events for the wrong
level when synchronizing technologies. Both of these issues are related
to failing to accunt for the unlocked level being one less than the
level stored when the researched property is false.
