some of the script's output won't be accurate anymore; but it's not data
that we actually need (and we haven't needed it for quite some time) so
that shouldn't bother anyone. the generated keymap, assuming that still
works, should be fine though :)

as desired, it is possible to hold the sticky key down for short number
runs and it is now a more frequently used key that toggle. Also added
notes about mac keycodes that I found in search of play/next/prev
buttons. I suspect that codes need to be inserted into the USB data
stream to indicate that a media key is being pressed.
the behavior for transparent keys not affecting sticky key state was
broken because kbfun_transparent() was only getting called for key
press and not for key release because the layer for the key was cached
on keypress. By caching the transparent key press result on key press
we can ensure that the main_arg_trans_key_pressed is set correctly for
any key function called on key release
kbfun_press_release_preserve_sticky() is meant to replace
kbfun_press_release as the function used for standard modifiers (shift,
control, alt, and gui) so that the sticky state is preserved and it is
possible to key in chorded commands using a key on another layer
pressing the keys in the chord one key at a time simultaneously without
breaking the sticky state. (e.g. ctrl+F2 as lsticky2, ctrl, x [where x
is defined as F2 on layer 2]
TODO: Noticed a bug where the transparent behavior does not work as
expected for modifiers. lsticky2, ctrl, x does not produce ctrl+F2 when
ctrl is defined as transparent on layer 2 and keycode=ctrl,
press=kprrel, release=kprrel on layer 0.
sticky layers in the one time state were being popped anytime
kbfun_press_release() was called, which should only happen if the key
was defined for the sticky layer, i.e. kbfun_transparent() was not the
first function mapped to that key in the topmost layer.
