Rework input handling (#345)

* Refactor input systems (closes #173)

* Add color_test example

* Add support for redirecting events to non-window contexts

* Actually respect EguiGlobalSettings

* Remove web_sys_unstable_apis, fix docs and tests

* Fix windows build

* Disable the headless test (broken after a Bevy update)
