Web bugs march25th

A bunch of fixes from last week's permissions testing:

 - #10585: Show all images in Dataset (don't filter by the current user / Dataset owner)
 - #10562: Fix creation of P/D in tree when in "All Members" view.
 - #10586: Reset rendering settings fixed in 'Read-edit' group.
 - #10587: Datasets or Plates 'Remove' -> correct place in tree (not under Orphaned)
 - Also, creation of Projects / Datasets / Screens should now place them in the correct position in the tree, instead of just at the top.
