Improve UI for item deletion

The UI for deleting a vault entry is a bit awkward (and often hidden from view!). Currently one must:

  • click to view the login details
  • click to edit the login
  • scroll waaay to the bottom of the panel (often not visible…new users may not even know it’s there)
  • click to delete the login, and confirm

I propose:

  • in “View” mode, change the upper right link from “Edit” to “Edit | Delete” (two separate links)
  • in “Edit” mode, change the upper right link from “Save” to “Save | Delete” (two separate links)
  • remove the “Delete Item” link from the bottom of the edit panel
