Fixed face recovery using CPU too often on systems with mid-range GPUs
Greatly improved face recovery memory usage and performance
Fixed many causes of Photoshop plugin not being found, returning errors, or not opening the app
Fixed transparency handling in Photoshop plugin
Fixed processing errors on certain images when using face recovery
Fixed square artifacts in output on Mac
Fixed various errors during batch processing
Added more specific information to error messages

Defined as Bronze due to missing useful Face Recovery feature and instability plus slow model loading when using CPU.

Perfectly usable on NVIDIA GPU without that feature however.
