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.
Be a bit more accurate in the online time stat name and call it for what
it is. It counts time spend online on the server, not necessarily
time spent playing.
Add command that extracts play time (and players) from the currently
running save to the recorded instance statistics. This is useful for
getting correct play time statistics when an existing save game is
imported.
