add stylized lines to lua
the exported do_menu has a severe limitation of 64 items
it also requires double the memory
put_line is the way rockbox builds menus
update printtable
user config from core -- done
code cleanup
fixed for 1-bit screens
changed button behavior
fixed for 2-bit screens

add defines for sound functions
SOUND_VOLUME, SOUND_BALANCE, SOUND_CHANNELS, SOUND_STEREO_WIDTH ...
defines depend on target
require "sound_defines" to add them to rb.sound_settings[]
consolidates:
sound_set, sound_current, sound_default, sound_min, sound_max,
sound_unit, sound_pitch, sound_val2phys to a single function
rb.sound("name", setting, [value])
require "sound.lua" for old functionality

This library allows events to be subscribed / recieved within a lua script
most events in rb are synchronous so flags are set and later checked by a
secondary thread to make them (semi?) asynchronous.
There are a few caveats to be aware of:
FIRST, The main lua state is halted till the lua callback(s) are finished
Yielding will not return control to your script from within a callback
Also, subsequent callbacks may be delayed by the code in your lua callback
SECOND, You must store the value returned from the event_register function
you might get away with it for a bit but gc will destroy your callback
eventually if you do not store the event
THIRD, You only get one cb per event type
["action", "button", "custom", "playback", "timer"]
(Re-registration of an event overwrites the previous one)
Usage:
possible events =["action", "button", "custom", "playback", "timer"]
local evX = rockev.register("event", cb_function, [timeout / flags])
cb_function([id] [, data]) ... end
rockev.suspend(["event"/nil][true/false]) passing nil affects all events
stops event from executing, any but the last event before
re-enabling will be lost, passing false, unregistering or re-registering
an event will clear the suspend
rockev.trigger("event", [true/false], [id])
sets an event to triggered,
NOTE!, CUSTOM_EVENT must be unset manually
id is only passed to callback by custom and playback events
rockev.unregister(evX)
Use unregister(evX) to remove an event
Unregistering is not necessary before script end, it will be
cleaned up on script exit

Rockbox constants are auto generated by a perl script like the majority
of the plugin functions.
Constants are contained in rb_defines.lua, if the file exists it is auto loaded
by the lua state for backwards compatibility
