A simple plugin to install fallible systems to bevy

## API

Library provides two main components: `#[fallible_system]` attribute macro and `SystemErrorEvent` struct.
Essentially, every *fallible_system* will generate a `SystemErrorEvent` event if it results in an error, and that's about it.

For simplier usage, there is `fallibleSystemPlugin` to register everything you'll need to recieve error events.

## Example

```rust
// Some system that might fail
#[fallible_system]
fn system(asset_server: Res) -> anyhow::Result<()> {
let handle: Handle = asset_server.load("texture")?;
}

// Let's make another system to read every event about other
// systems failures and report !
#[derive(Default)]
struct ReportSystemState{ reader: EventReader }
fn report_system(mut state: Local, mut events: ResMut>) {
for event in state.reader.iter(&mut events) {
println!("Error in {}: {}", event.system_name, event.error);
}
}

fn main() {
App::build()
.add_plugin(fallibleSystemPlugin)
.add_startup_system(system.system())
.add_system(report_system.system())
.run();
}
```
