Subject: games/opus-magnum: Update to latest version

Upstream changelog summarized:

 * Switch to DirectSound on Windows.
 * Remove iron-on patch link.
 * The Hexstabilized Salt puzzle now requires 18 outputs instead of 6.
 * Add a new journal issue that is entirely production puzzles.
 * Add a hidden option that will hopefully fix some of the sound issues
   that were introduced when we rewrote our audio backend.
 * Add a new issue to the journal with some "battlefield medicine"
   themed puzzles.
 * The game's content files are now opened as read-only, which should
   hopefully fix some of the antivirus-related crashes some players have
   been experiencing.
 * Atom spawn/consume effects on glyphs are now cleared when the
   simulation is stopped, which should fix a bug causing "ghost atoms" to
   linger on the board.

I've made this summary by picking the relevant parts of the upstream
Steam announcement page at:

  http://steamcommunity.com/games/558990/announcements

The best part about the changes is that content files are now opened
read-only, so we can finally drop all that patching. This also is the
first time I can say something positive about AV software, so thanks for
bugging Zachtronics into fixing this issue for Nix as well :-)
