ef34126913 lua add better memory stats
lua gives you a memory used number that only reflects the current allocations
if fact it doesn't even give you a way to get the amount of ram free

rb.mem_stats() seeks to fill this gap by marking the memory allocated for lua
with a sentinel value which can later be checked to get a high water mark
of the ram used by lua and a pretty good idea of how much ram is available

Also includes an example script
usage:
used, allocd, free = rb.mem_stats()

80c3b84e08 lua Add scrollable stack traceback WIP
lua currently splashes a stack traceback on error
for deep tracebacks and especially on devices with smaller screens
this leaves out a lot of vital information

in the past I have resorted to splitting the traceback string or
even saving the return to a file

This patch provides a scrollable buffer with rudimentary text reflow
to allow you to read the whole traceback string

Upon traceback if you press nothing the screen will display for 5 seconds
If you press OK or CANCEL it will quit immediately
PREV/NEXT scrolls the list on button press timeout is disabled

lua now provides rb.splash_scroller(timeout, str)

example script provided too

1c0648c603 lua rockevents reduce context switching for action and buttons
check if any buttons are waiting in the queue before triggering
the event thread for action & button events

makes button events quicker and also spend less time interrupting lua
both wins

018e0051bc lua playback example
cool little lua based audio player
creates dynamic playlist of 10 mp3s found on device if no music loaded

I had to limit the depth of search to 3 levels due to the recursive
nature of the current dirbrowser functions this could be rectified with a
bit more code

fixed a bug in print.lua that kept scrolling text even after screen clear

267d04d2bd Lua add metadata and settings reading helper module
Adds example scripts for reading track metadata + dumping albumart
and rockbox settings

settings are now stored as a table of strings rather than a table of tables
as it saves ~15 kb of ram without adding much complexity
