feat: app.hide() and app.show()

[probablykasper]

Would be nice to have the ability to hide the app, so that the app loses focus, just like the MyApp > Hide MyApp menu item. Mostly useful for macOS

Does https://docs.rs/tauri/1.0.0-beta.2/tauri/window/struct.Window.html#method.minimize help?

[probablykasper]

@lucasfernog Sadly not, because the minimize and hide methods don't make the app lose focus on macOS (and they probably shouldn't by default)

I saw something similar to this with electron before, let me check.

Edit:
This is a workaround for focus issue. https://www.github.com/oliverschwendener/ueli/tree/dev/src%2Fmain%2Fmain.ts#L231

And this is electron docs
https://www.electronjs.org/docs/api/app#apphide-macos

Yeah electron seems to have app.show and app.hide for macOs only and they are a bit necessary for overlay-apps imo.

@amrbashir tao seems to already have what's needed for app.hide() to work:

tao/src/platform/macos.rs

Lines 453 to 457 in 73c7aac

	fn hide_application(&self) {
	let cls = objc::runtime::Class::get("NSApplication").unwrap();
	let app: cocoa::base::id = unsafe { msg_send![cls, sharedApplication] };
	unsafe { msg_send![app, hide: 0] }
	}

Tried exporting it in tauri, but can't wrap my head around how all the traits work :/
