AutoHotkey script to map Caps Lock to Escape when it's pressed on its own, and Ctrl when used in combination with another key, à la Steve Lo

AutoHotkey script to map Caps Lock to Escape when it's pressed on its own, and Ctrl when used in combination with another key, à la Steve Losh. Adapted from the one that does something similar with the Ctrl Key on the Vim Tips Wiki (http://vim.wikia.com/wiki/Map_caps_lock_to_escape_in_Windows?oldid=32281).
