Fixed even more sql errors :)
Merge branch 'master' of https://github.com/InfectedLan/InfectedAPI
Added support for looking up city name from postalcode during registration.
Make sure we don't have duplicate email address, ecpecially since this can be used instead of usernames now.
Because of an refactor in the datebase we don't need strtolower and ucfirst manipulation in CityDictionary anymore.
