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.
Add factorio.enable_save_patching config entry to allow disabling the
save patching done on startup. This is for running vannila games or
scenarios that are not compatible with Clusterio.
Change module loading to use a module.json file describing the module
and patch in all files in a directory path passed to the patcher instead
of having to pass the files names and their content. This allows the
specification of which files should be passed to the event_handler lib
and an easy implementation of loading stand alone modules.
