Upgrades the code to Bevy 0.12

Thanks for this. I'll take a proper look tomorrow and make sure everything runs fine, but should be good.

Could you also update the version table in the README?

Done 😉

I'm not sure why, but when I try to run the examples on this branch I get a compile error in bevy_reflect:

error: could not compile `bevy_reflect` (lib) due to 2 previous errors

I couldn't find anyone else having the issue, and the bevy examples compile fine for me, so not sure what's going on here.

I too am interested in seeing debug lines on 0.12, so I cloned the repo for this PR and tried it. I did not get the error you got on any of the examples. Instead it just worked. The only hickup was that I needed to switch to the fix/upgrade-bevy-0.12 branch.

Could you verify that the examples don't work for you after switching to that branch?

Edit: To take this testing further, I integrated the repository into my own personal project using cargo's patch feature, and it works just as I would expect it to under Bevy 0.12. I plan to build off this branch's work to update to Bevy 0.13.

This does indeed seem to work now. Sorry for the delay. I've merged it manually since I had to do some commits to update the readme etc.

Thank you!
