Add onChange support for inputs

[FoamCactus]

onChange events are supported by web_sys and stdweb and are easier to work with than onInput events for a lot of things

@FoamCactus previously it has the onchange supported however I have an issue if I wanted to use onInput although onchange was not set because of this I removed, I don't remember exactly but I can create a branch and reproduce it and we can see with yew community

I think I have a working branch I just can not for the life of me get the tests to run. If you can provide guidance on that I can fix any other issues the branch has @dancespiele

@FoamCactus could you tell me exactly where is the error that you have? you can execute test like this in the root folder

wasm-pack test --headless --chrome --firefox crate
