Show you the code? You want me to show you code?! Here you get some
code!! Player users: you loose again for the moment as I only own a
recorder...

This is a first throw of the core engine for user assignable keys.
Note that it is only the engine. There's no text file parsing yet.
Neither there is a pearl script or something equivalent that generates
source files with the available commands. That's the two things that
have to be done. After that we 'only' have to adapt the rest of the
code where button handling still is hard coded and make a working
factory preset for all that.

To demonstrate the functionality I chose a new little tool I always
wanted to have: a gui for splitting mp3 files.
No, we can't split files yet since we don't have file writing and the
split editor still has its problems. So just see it as an example
here.

How it works:
While a song is playing select the menu entry 'split editor' from the
main menu (It doesn't belong there and won't be there in any official
rockbox version).

play button: hit it to pause / resume playback
play button: hold it to reset pitch
left / right button: move around the split point cursor
up / down : zoom the osci
on + right: 150% pitch
on + left: 50% pitch
F2: toggle between three playback modes:
    - loop from the split point
    - loop to the split point
    - loop over the split point
off: quit the split editor

All these key bindings are done just as if the were read from a file.
I am convinced that this prooves that the mechanism is flexible and
once we have the real file format and the real mechanism for
generating the command lists you will notice that they are fairly
simple to use for both, the programmers and the consumers.

With these key schemes two other things are gained: Now it's
incredibly simple to make user definable menus and we can define
macros that execute servaral commands with only one button click. That
could be used eg for one-touch equalizer presets, etc

So don't you cry "Show me the code"!

P.S.: apply the patch, all other files go into apps
