A simple mod to take an autosave at every hour of gametime, with a configurable save name prefix.

Features

• Saves are timestamped with the gameplay time using 5+2-digit hour+minute
  0-padded timestamps (e.g. 00012h05m), which ensures that the lexicographic
  order of the save names is equivalent to their chronological order (read:
  sorting the saves by name also sorts them by playtime)
• Saves are named with a custom prefix that can be specified per-game, and the
  mod will remind you if it is unset at the start of a new map
• Timestamped saves can be manually triggered via a shortcut bar button or a
  keybind, with a user-supplied suffix added to their name (note: can only be
  done by admins in multiplayer, as the saves are made on the server-side)
• Save interval is configurable, and can be changed on-the-fly in a running
  game
