Native Linux version, not-an-update

I am happy to announce that POSSESSOR is now natively-playable on Linux. I hope this will please the followers of the mighty Penguin. Mind you, I haven't tested the x86 version (due to not having anything to test it on at hand), but it should work. Hopefully.

The Windows version is now downloadable both as a 32bit and a 64bit app. Just in case there's that one person somewhere in the world who still runs a 32 bit Windows and really wants to play this game.

Also, I used this opportunity to fix a couple of tiny, tiny issues. One, every single SFX contributor is now properly credited in-game (a couple have slipped by me in the pre-submission rush, for which I wholeheartedly apologise!). Two, a couple of annoying typos were fixed.

I am planning for this version to be the Final, Definite(tm) 7DFPS Jam Edition of this game, which will be kept here forever (or until itch.io ceases to exist) for posterity's sake. Any following updates will be downloadable as separate files, fresh and clean.
