Bugfix: adding more edgecases

[jacobgarder]

Adding some more edge-cases where the API is not using strict camelCase:

"surrogate_ip" should translate to "surrogateIP"
"surrogate_ip_enforced_for_known_browsers" should translate to "surrogateIPEnforcedForKnownBrowsers"

Also replaceing the if-statements with a dictionary for translating edgecases.

Thanks for this contribution.

If we keep finding more edge cases relating to the word 'IP' then we should write something that will handle it for all cases.

Happy to add this for now as it's not exactly onerous to add a few more if we find them.
