Upgrade to Bevy main, in preparation for 0.6

[rezural]

This is a chase the errors upgrade to latest bevy main.

I am not sure if there are architectural changes needed, or subtle errors introduced, as this is the first time looking at this crate.

The examples work, so that is nice.

Thanks

Would you be okay if I were to leave this open until 0.6 gets released?

[rezural]

Of course, this is just the result of me playing around with bevy main. There's definately some more changes to be made:

• docs
• usages of AppBuilder in examples (IIRC)

0.6 has been released! 🎉

Changes look good, would love to see this get merged!

[rezural]

I have added 3 commits, that update the README, method documentation, and the src/client.rs, which was causing an error on latest main (not 100% sure this is needed for 0.6).

[rezural]

I have updated the dependency to bevy 0.6, and also rebased onto main.

Should be good to go.

@rezural thanls a lot for your work, it works nicely.
Could you update the Bevy Version Compatibility in the README.MD too?

Quack,

@TheNeikos is there any remaining blocker?
I've tested this patch on my project and it works nicely.
