The python library always loads all images in the known people folder

Once there are a gazillion images, that will definitely be a problem. Probably should cache those images and refresh the cache from time to time.

On startup, pre-load all images using https://github.com/ageitgey/face_recognition/blob/master/examples/recognize_faces_in_pictures.py

and save them in a dict for easy name or image compare.

I wonder which would be better. Calling the compare_faces with a list of encodings and then looking through the array to find the first True... or have a dict and call it with a single image multiple times.
