More placeholder sounds from Freed∞M & Blasphemer?

[SenhorFlibble]

A while ago I compiled a selection of placeholder sounds to fill in the missing gaps in Open Quartz, for my personal use, from the Freed∞M & Blasphemer sounds. As far as I can tell, the licensing in both projects should make them compatible with LibreQuake. These include entire sound sets for the Ogre, the Death Knight, the Zombie, the Shambler, boss1 and boss 2, as well as some sounds from the plats and doors folders.

If you want, I could upload them and make a PR. I believe that placeholders are better than no sounds at all, and I tried to make the sets sound at least remotely consistent for each monster (although YMMV I guess).

Also an a related note, it was mentioned in a discussion of a different issue that although GPL assets are not compatible with the LibreQuake license, they could be included in actual binary releases with a note that some assets are licensed differently. If I understood this correctly, I was again thinking about placeholders -- Open Quartz has a reasonably workable "ghost knight" stand-in, and there is a GPL Ogre model (which somehow did not end up in the Open Quartz project, although I think that it was created for it) that can be found here. Granted, they absolutely fall out of the general art style, but from the player's perspective a fully animated enemy model should be more preferable to a static silhouette that is much less readable and provides far less real-time feedback to the player. I'm suggesting this only because LibreQuake is already very playable with a good number of well-designed, interesting levels, and having a full set of game assets, even with a proportion of placeholders among them, would provide an almost-complete playing experience for the time being.
