Gamepad device events - Web/WASM (#1414)

Add gamepad support for stdweb and web-sys, as well as web-specific gamepad examples. * [web] Fix compilation error from device api * [wasm] Apply device api changes * [wasm] Format and cleanup * [wasm32] Implement gamepad connections * [wasm] Harmonize * [Test] Made some tests with wasm-pack * Quick fix instant non supporting Hash trait * Fix on_received_character * [web_sys] Split add_event and add_window_event * [web] split device implementations * Update tests/web...still does not work * [tests/web] do not ignore index.html * [web/web_sys] split canvas and window * [tests/web] enable stack trace * [web] fix borrowmut * [web_sys] fix gamepad registration * [web] harmonize naming * [web_sys] create global emitter * [web] implement gamepad buttons * [web] implement gamepad axis * [web] cleanup * [web] update test * [web] move tests/web to examples/web * [web] axis does produce stick event * [web] Support Stick event * [web] implement gamepad to stdweb * [web] rename examples/web to examples/wasm * [web/web-sys] Move gamepad_manager from backend * [web/web_sys] implement EventLoop::gamepads * [web/web_sys] Drain gamepad events * [web/stdweb] apply web_sys changes * [web] update web/examples * [web] move gamepads code to gamepad_manager * [web] simplify and optimise * [web] replace EventCode to GamepadAxis and GamepadButton structs * [web] reuse gamepad events due to chrome issue * [web] rumble does not work * [web/stdweb] try debugging * [web] fix Chrome gamepad not updated * [web/stdweb] created an example * [examples] fix paths * fix warnings * [web/examples] update comments * [web/stdweb] add experimental support to vibrate() * [web] add CR
