Deforminator: minor patch

1. Changed save pattern functionality (loads into next available slot)
2. Next available slot starts at 2 (saves reference pattern in  slot 1)
3. added ‘delete’ keyboard shortcut (replaces the current saved node
pattern with the one on screen)
4. added load file path text display at top of image
5. reintroduced notes and subject initials prompt (occurs on save)
6. Added backwards compatibility for Deforminator_PIL (since i’ve added
function inputs and outputs, this version ensures previous saves with
less outputs will run)
7. File saves now go into the target save directory
8. target directory and loaded file path now included in save file
