Add startup event to the Clusterio module API which is raised at startup
of a Factorio server. This is to server as a replacement for the
on_init and on_configuration_changed events which cannot be used in
modules.
Adds clusterio_patch_number global from the patcher in order to
implement this. This is a number that's incremented every time the save
is patched.
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.
Remove Hotpatch and implement a save patcher in its place. The save
patcher takes a normal Factorio save and adds modules to it that's
loaded by a generated control.lua file. This greatly reduces the
difficulty of adding an existing game to Clusterio and using scenario
code in plugins.
The mechanism for selecting what code to patch into the saves from
plugins is temorary and expected to change with #220.
