create "userdata" folder for allowing customizations

[Williangalvani]

Currently works with custom css files located in the host's /home/pi/userdata/user_style.css`

The screenshot uses these updated variables:

:root {
    --v-primary-base: #dd8603 !important;
    --v-info-base: #dd8603 !important;
    }

The full list (courtesy of somewhere in chrome's dev tools) is here: (upload when chrome is happier)

I intend to use the same or a similar mechanism to allow overriding images/models.

from meeting:
try loading a "model-override.glb", if it is not available, fallback to frame-specific

change to theme-style.css

[Williangalvani]

add support for default firmware, default parameters.

nice!

thanks, I'm pushing some other stuff for the vehicle setup in here, but i'll probably remove it to add it in another pr later on. I'm just making sure everything works the way I expect first

change to theme-style.css

Is this still planned in this PR?

It makes sense to disable cache, makes development easier... And I don't think it would impact that much on loading performance.
