Changed the syntax for keymap%'s map-function. f a modifier is not
mentioned in a state string, it matches states where the modifier is
pressed or not pressed. A tilde (~) preceding a modifier makes the
string match only states where the corresponding modifier is not

Changed keymap%'s add-key-function and add-mouse-function to
add-function (eliminating the different namespaces for key and mouse
event functions).

Removed keymap%'s set-error-callback; the keymap errors are instead
reported by raising an exception. The exception handler can't escape,
but it can at least print the error to the current error port.
