This is about the only thing left preventing us from running the main web view on react in a similar way the primary display is run. (rather than screenshots)
The theme wizard (while editing a theme) now changes both background_source and background_filename then sets filename to the new cache location on apply (also added the filename_source var to Theme). The new var is needed so when the user goes to change the theme again, they see the file they selected, not the cached one. This commit fixes the issue of changing theme backgrounds not deleting the cached file but deleting the original file.
