Add ability to upload personal image as reference

[ellend23976568]

1) Add a place to upload personal images off computer so Firefly can use those as reference

2) A way to go back to previous generations of image

3) Work on more realistic eyes when prompt calls for realism - real eyeballs have viens and shadows
