Rework client.js to support running multiple instances at once and be
managed remotely and implement the neccessary communication
infrastructure for this.
Due to circular dependencies on the implementation of this the master
branch is significantly broken after this.
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.
