Add a list of constants for event.which or .keyCode

[ubershmekel]

E.g. spacebar, pagedown, enter, etc. These are all buttons commonly used that are coded with magic numbers (e.g. 32 instead of SPACE_KEYCODE, or 38 instead of ARROW_UP) all over the web. I think it would be nice if there was a way to standardize this instead of having to use a "cheat-sheet" e.g. ​http://mikemurko.com/general/jquery-keycode-cheatsheet/ to read such code.

I understand certain browsers have different conventions for these ​http://unixpapa.com/js/key.html but perhaps a function for normalization of keycodes can be added as well.

This would be great for a plugin, but would all a lot of bytes to core for something that isn't needed by everyone.

jQuery UI provides a list of common key codes: ​https://github.com/jquery/jquery-ui/blob/4aafdfd10b8d29288a81ca7a40d22d5bd5954a92/ui/jquery.ui.core.js#L26
