Model level background and theme options

[pfeerick]

I think both the theme and background image should be configurable at the model level, not just globally.

• At present the background image / "wallpaper" is being sourced from /THEMES/EdgeTX/background.png. I think instead it should be coming from /IMAGES/background.png so we can delete that /THEMES/EdgeTX folder since that is all that is in it.

• Then, the background image can be sourced from:

• if set, model, else

• if present, theme, else

• global

Thus allowing a user to also override the theme provided image (when present) on whim. Probably also be nice to make it so use of the image can be disabled if you don't want to show/use the theme provided image.

• And for themes, it would be global theme, unless configured at the model level.

That's exactly @peter how it should be.

AD "Per model" theme setup.
If we include "Selected Theme " in modelXX.yml defintition it should also nicely syncronize with Companion as for now it seems to sync you need to copy selectedtheme.txt from /THEMES/ folder
