This commit introduces an alternative to specifying key bindings as a combination of key modifiers and a character. It allows you to specify an explicit virtual key as `vk(nnn)`.
Additionally this commit makes it possible to bind actions to scan codes. As scan code 41 appears to be the button below the Escape key on virtually all keyboards, we'll be able to bind the quake mode hotkey to `win+sc(41)` and have it work consistently across most if not all keyboard layouts.
