Add image paste fallback

update opencv package inside requirements.txt

Save Optimizer next to TI embedding

add missing state info

add api logging

better targetting, class tabs was autoassigned

Add more latent upscale modes

Save full resolution of intermediate step

Comma was causing the the value in PNG info to be quoted, which causes the upscaler dropdown option to be blank when sending to UI

failing to load model weights from settings won't break generation for currently loaded model anymore

I moved a preset manager into quicksettings, this function
was targeting my component instead of the tabs. This is
because class tabs is autoassigned, while element id #tabs
is not, this allows a tabbed component to live in the quicksettings.

ui: save dropdown sampling method to the ui-config

Fixes Firefox pasting support
(and possibly other browsers)

added footer
removed unused inpainting code

Also add check to load only .PT and .BIN files as embeddings. (since we add .optim files in the same directory)

The old 'opencv-python' package is very limiting in terms of optical flow - so I propose a package change to 'opencv-contrib-python', which has more cv2.optflow methods. 

These are needed for optical flow trickery in auto1111 and its extensions, and it cannot be installed by an extension as only a single package of opencv needs to be installed for optical flow to work properly. Change of the main one is Inevitable.
