serious problems with using the LEDs

(1) the LEDs are inside the lens cover, opening the lens cover to see the torch activates the camera app.
(2) there are no LEDs on n8x0

now, 1 could be handled by addition of a UI element in the camera app itself.
a toggle switch for the backlight.
there are times im taking photos and I need the light on to see, instead of it just coming on for a second or so to focus.

we could lockout or otherwise prevent the camera app from opening, but i think thats wrong too, it makes it confusing and tricky to manage and I bet we would get it wrong
so as a proof of concept, it should be entirely possible, but in practice it would be more tricky.

patches welcome, liqtorch is in extras-testing and code is floating around in github (liqbase-playground repo) or just grab from the maemo.org source repository.
