  constructors for `geoip.webservice.Client` and `geoip.database.Reader`.

Fixed packaging issue

API Change

* IMPORTANT: `geoip.webservices` was renamed `geoip.webservice` as it
  contains only one class.
* Added GeoIP2 database reader using maxminddb. This does not work with PyPy
  as it relies on a C extension.
* Added more specific exceptions for web service client.
