Investigate some sort of fuzzy matching to improve food.gov hit rate

[dutts]

The main cause of no results is differences between the name used on the takeaway website and its listing on food.gov.uk results.

Investigate if it would be possible to perform a lookup of the address postcode instead and then attempt to fuzzy match the search string with the set of returned results.

Would need to feed this back to the user, possibly through a tooltip over the result or something to provide details of the original food.gov.uk to help identify mismatches.

https://github.com/krisk/Fuse looks good, need to make sure we'd still pass AMO with this as I believe it operates a white list of approved libraries that are shipped with extensions.
