Initial commit
Finetuning of icons
Added settings page and logic for image quality (jpg and jpg+raw)

With quality=jpg+raw the raw bayer data is append to the generated jpg.
You need a program like raspi_dng to convert this jpg to a dng file
which can then be processed with any raw converter (e.g. Rawtherapee).
