Update blaster.h

Don't Jam if empty. Autofire now counts bullets (uses WavLen of auto.wav per shot ! ) If already full, Reload plays full.wav.

Is this still a thing, or should I close the PR?

I have a working personal version, but I think you disliked some stuff about it. This PR is a piecemeal, trying to make it better and still work, but I think I hit a wall. Might need some help, might be better to submit my "I'm happy with it" version in a separate PR then compare and combine what can be used and what should change. It's going to take a bit of effort. Time is slim these weeks, so asap, I'd love to work on this again.

TL;DR yes still a thing.

So I think it might be best to leave the default blaster prop as is, and just make customizations to a new file altogether and call it blaster_BC_buttons, just like how we do for saber prop files. That way, all changes can be made and reviewed in one place, and options and features included aren't "forced" on everybody
