Support for hashing image segments will be the most straightforward way of handing screenshots-of-image matching.

the watershed segmentation bit will suck really bad to implement efficiently in javascript but I'll give it a try!
looks very promising according to the paper

@bethylamine I added cropResistantHash, hopefully this is useful for screenshot-of-images!
In the same commit I micro-optimised the phash function (~60% faster on my browser) so you should update even if it turns out that cropResistantHash doesn't work great for the extension :)
