[feat, Kobo] On Kobo, drop fb to 8bpp on startup (#4637)

Browse Source 
* The Great 8bpp Experiment

Swap to 8bpp on Kobo, because we're 'effing grayscale, for pete's sake!

* Always swap to 8bpp, no matter the launch method.

Because it turned out that, even when restarting Nickel, we had to
restore the expected bitdepth ourselves, because pickel/Nickel didn't do
the job completely.

(I'm going to guess the grayscale flag wasn't getting flipped properly).

* Dither every non-transparent icon to the eInk palette

* Make sure hasBGRFrameBuffer is only enabled when the Kobo fb actually is
@ 32bpp...

* Re-process badly grayscaled icons

* And re-grayscale that one w/ gamma correction so the squares show up
better.

* Allow the fbdepth switch to be disabled (in Developer settings).

Also, allow setting debug mode that way.

Also, forcibly disable verbose logging when disabling debug.

* Update setting name to piggyback on the existing check in reader.lua

* Update icons postprocessing info
