This allows CGEventTap callbacks to capture (drop) an event entirely. This is useful for implementing system-wide hotkeys, among other things.
This PR is essentially a rebase of #492. While releasing the breaking change in #710 we might as well include this, since users of CGEventTap will need to update their code anyway.
Closes #492, #664, #665.
