Night mode: keep some images non-inverted

Browse Source 
Have the code pre-invert some images when in night mode,
so they get inverted back to normal by night mode.
This will allow images to be displayed normally in
the following contexts:
- images in credocument pages
- long-press on images in credocument viewed in ImageViewer
- cover thumbnails in File browser and History
- full size covers when viewed in ImageViewer
- images in Wikipedia lookup results
