Fix bug in Rhai Event Handler

[zwazel]

This should fix #75

Also added a new example for Rhai.

I just noticed that i also updated the Rhai version. please tell me if I should revert this change or not.

[zwazel]

I also just changed it so that i no longer get errors printed out when a function can't be found in a script.

as far as i can tell, this is a similar behaviour as in the Lua solution:

bevy_mod_scripting/languages/bevy_mod_scripting_lua/src/lib.rs

Lines 169 to 172 in 7590248

	let f: Function = match globals.raw_get(event.hook_name.clone()) {
	Ok(f) => f,
	Err(_) => continue, // not subscribed to this event
	};

Hi @zwazel PR looks good, great catch! Love the examples. Please see to the clippy errors and LGTM

[zwazel]

Glad I can help with this great crate!
I currently can't go on my PC, so i'll fix the clippy errros tomorrow!

I might also take a Look at how to tackle #75

Just saw your comment on it, will Look at it later. On mobile right now.

Appreciate it a lot! no problem!

Hi, as far as I can tell the only clippy warning that I got was from lua derive.
(I actually didnt get any locally, so kinda hard to reproduce, but that should have fixed it)

Yeah sorry about that, the CI runs on latest rust version meaning any new clippy warnings randomly popup on old code, I need to find a way to pick the clippy version somehow
