Upgrade to new upstream version code of tyrquake

[palmerj]

version 0.70 is out now https://disenchant.net/tyrquake with lots of improvements. Anyone thinking about upgrade this port?

Unfortunately, tyrquake libretro is pretty heavily modified, AFAIK, so it would take a complete re-port and would likely lose a lot of libretro-specific features.

That's unfortunate that the project hasn't been setup to more easily take updates from upstream.

Actually looking through the commit logs @inactive123 has been doing selective backporting which is good news. Would have been nice to get the new features ported in through. e.g hudscale.
