Feedback for skip, interrupt, and cancel

[Kavukamari]

sometimes I'm not sure if the program has actually received my input for stopping generation, it would be nice if the console or UI would indicate that it's going to cancel soon

I'm pretty certain it always gets your input, but cancel will happen only after current iteration ends and if you press "skip" on the last iteration of the current image, then the next image generation will be skipped instead. Its a bug, surely.

Might also help to clear the memory, input manual garbage collection and VRAM clears. Interrupting a model training leaves it using 66% VRAM so that pressing resume ends in CUDA OOM. Resuming training from that point (relaunch) will give you some collapsed results (muddy, watery or just random colors).
