yes, but we still need to somhow define the actions which can be returned..

so ive been playing a bit more and i tihnk it might even work :D (even
on the ipod!)
(i've also neatened it up because it was painful to read before)
Ignore the 4th column, I thought it might be needed, but after playing
around I dont think it is anymore.
ACTION_BACK has been removed as it almost always is the same as
ACTION_LEFT and ACTION_LONGMENU has been added (couldnt tihnk of a
better name, ideally used for the quick menu and not sure whereelse.)

};

this isnt flawless because the wholething falls over when I tihnk
about the colour chooser window (ipod would want ACTION_UP/DOWN to
adjust the bars where iriver and other would use left/right), but I
still belive that having more generic code in 99% of the ui and having
to fiddle a bit in the last 1% is better than the existing system.

Pretty please will someone comment on the overall idea?
