Follow-on to 5fca371a616dba16f955087c4477ee229ee222d0 for #1945.
Previously skipped admin_watermarks mods to use new functionality of #1945
since there was concurrent work on it with #1970.
Now that both are done, we can wrap this up.
#1982 - Add placeholder for albums with no album cover.
- Added missing_album_cover.jpg placeholder image.
- Modified the graphics helper to use it.  Calling graphics::generate will copy it.
- Modified item::remove_album_cover and gallery_event::item_created to run graphics::generate.
- Added unit test to Graphics_Helper_Test.
#1983: Remove item keys changed for/by graphics::generate from significant changes list.
There's no need to run through all of the item save/validation logic for these
entries, which are changed frequently during the course of thumb/resize generation.
