Add ModPack data type with corresponding storage on the master, messages
to create, update and delete them, as well as commands to invoke them.
The ModPack data type contains a list of mods with versions and optional
sha1 hashes, and mod settings to be used.
Add the ability to manage a set of mods to be shared by the master
server to the rest of the cluster. This implements storage, uploads,
downloads, deletetion, and listing details of mods but does not actually
do anything with the stored mods.
Add ability to move or copy saves between instances. For instances on
the same slave the saves are transferred with filesystem operations, for
instances on two different slaves the proxy stream interface is used to
send the save via the master server.
There are some corner cases with streams that cause them to not emit
finish close or end events which in turn means that code liseting for
these events directly may end up hanging forever. Use stream.finished
to detect end of streams which will handle these cases correctly.
Instances require a number of modifications leading to it not being
able to be converted into a function. The main one is that there is a
list of config elements that cannot be set via the edit command and
either have to be set via different means or cannot be set. To stop
these fields constantly sending error messages, we disregard adding them
to the file in the first place.
Using an event emmiter, the fields can now be set correctly in the
master config. Null values are now handled correctly, and numbers are also set
correctly.
Also now using the system described by Hornwitser, in using
libConfig.MasterConfig.groups to get definitions. Now all that's needed
is to re-read the updated data back into clustorio.
ctl master config edit [editor]
is the new structure; it can take an optional editor, and will prio this
editor over any other editor, such as one set by env vars. Generally,
the prio goes like this: argv supplied editor > EDITOR env var > VISUAL
env var. Things needing to be done are marked with a TODO.
