Change the background colour of the photowall via the config file

[oparoz]

When sharing an album, and later when embedding it, it could be useful to be able to set a background colour for that album and optionally all the sub-folders.
Per example, a white background doesn't work very well if the folder only contains designs or screenshots with a white background. An artist might want to hang all his painting on an orange wall, etc.

This introduces a new design section in the configuration

design:
  background: "f3088d"
  inherit: yes

The effect is not that dramatic, because you only see the background through the thin gaps between pictures, but it's still useful for some collections.

You're advised to use a custom CSS spinner if you configure the background colour of your albums as the default one doesn't look good.

Already in 8.2 and Gallery+ for 8.1 and 8.0. Works as expected. The feature can be enhanced in 9.0.
