games/itch: Add Towerfall Ascension

Packaging is a bit similar to what we had to do back then with Opus
Magnum (see commit 523dcef1f77251a4cfeb3428a0b13c0ec1d9c342) where some
game data files were tried to open in read-write mode.

I'm using the same patcher (which is using Mono.Cecil) that I have used
for Opus Magnum back then but I've cleaned it up a bit.

In the long term I'd try to make the patcher a bit more generic so that
it can be used for other Mono-based games, because opening game data
files in read-only mode seems to be fairly common among a few other
games I haven't fully packaged yet.

The game also tries to execute "xdg-open error_log.txt" in the event a
uncaught exception occurs, which then fails because no xdg-open is
available. So instead, I made a small dummy wrapper which just runs
"head" on the error.log instead.

Another thing which unfortunately is currently not working is the
editor, because it tries to create a directory ("Workshop") within the
game's content directory, which - again - doesn't work within the
read-only Nix store.
