Make the copy icons for username and password different in the item details screen

[pandelus (Alastair P)]

If find myself often clicking on the copy username icon when I meant to click on the copy password one.

Is it possible that the password one is tweaked in some way that it is different, perhaps a key icon.

Welcome, @pandelus! I adjusted the title a bit to be more clear since the icons are currently different in the main listing screen.
