This cleans up the hook file a lot and movesthe logic to seperate services
provided by MediaWikiServices. This also removes some setters and passed-
around variables and stuff. Also fixes the unit tests by not querying
external services anymore.

With this change, CookieWarning gets two new ways to limit the warning
bar to users of specific (configurable) regions. Based on the geo location
service (which can be configured, too, defaults to freegeoip.net), the
extension will try to get the region of the user (based on the IP address)
and checks it against the configured regions.
With the configuration variable $wgCookieWarningGeoIPLookup, the wiki sysadmin
can configure, if the lookup should be done with PHP (the timeout for the
request is hardcoded to 2 sedonds max), which will save the paylod sent to
the user, or with JavaScript, which will be asynchronous.
Deactivating this feature is easily done by simply setting the configured regions
to false, instead of an object.
