no more reWASD

Some players were using reWASD to have several people playing on a single keyboard.

You can now bind up to 4 players on keyboard/mouse (their respective inputs must be different from one another)

This can be useful over parsec or remote play if you don't have a controller, or if you want to exceed the remote play controller limit of 4 controllers connected (so you could theorically have 4 controller players and 4 keyboard players on remote play).

Don't hesitate to report bugs on the Discord server if you encounter any.
