Hello/Hi/Greetings,

I accumulated plugin patches of three installations that at least make the plugin settings available again. The plugins seem to work. Where applicable I submitted GitHub merge requests (not hoping that would be successful for plugins that haven't been touched for four years, but..):

AStat merged
GrumPluginClasses merged
piwigo-akismet merged
Piwigo-GThumb merged
Piwigo-Smilies-Support obsoleted
piwigo-videojs merged
Piwigo-virtualize merged
UpdateAlbum-Piwigo merged
read-metadata-plus

For plugins that are still in Trac or in no versioning system at all I did not bother to chase those down, but some are included in this patch.

Make sure your plugins are all updated to today's current, copy&paste the second code listing to a file, for example in your home directory plugins.patch and then cd into your piwigo/plugins directory and execute the command

patch -f -p0 -i ~/plugins.patch

And the patch is:
