Use the settings prototypes to coerce any incorrectly typed mod settings
to the correct type either by casting or by replacing the value with the
default value from the prototype.
This will fix cases where an update to a mod changes the type of ono of
its defined settings.
Due a bad order of operations when a host connection was closed the
event handler listening on "close" to remove the host from the
hostConnections mapping was added after the HostConnection's event
handler listening on "close" and invoking plugin hooks in response to
the host going offline. This in turn causes plugins that send
broadcasts in repsonse to thos hooks to throw an error due to the
broadcast sending code assuming connections that exist are valid target
to send messages to.
Fix by ordering the listener for the removal of the host connection
before the listener invoking plugin events.
Store and use a cache of the loaded ModInfo data to mod-info-cache.json
in the mods directory during startup. For simplicity this does not
cache mods added to the controller or host after startup, these get
added to the cache on the next startup.
If a bad download or file transfer causes a mod in a host's mod folder
to become corrupt the attempt to load the mod will throw an error that's
not the file not existing. This in turn causes starting the instance to
always fail as the mod is never attempted to be re-downloaded.
Fix by ignoring errors attempting to load mods already present in the
mods folder that aren't in the mod store so that a new download is
attempted after that fails.
It's possible to set the .icons to an arbitrary key value mapping
instead of an array and the game will still accept it. Convert the
icons to an array if it's an object mapping to handle this case.
Note that this doesn't preserve the order the game reads the keys in
because JavaScript reorders numeric key indexes on objects differently
to how the game orders them.
Implement the shorthand notations that Factorio recognises for colours
where individual components may be left out or the colour specified as
an array of values instead of an object.
