The "freegeoip" setting should be disabled by default

[Nicklas Nordborg]

The current service will be disabled on July 1st, 2018. It will be replaced with a compatible service that requires registration and the use of an "API KEY". It should still be a free service for basic usage. A BASE server admin need to set this up before the geolocation services are used.

For more information see: ​https://github.com/apilayer/freegeoip#readme

Basically the current setting that is:

http://freegeoip.net/json/{IP}

need to be replaced with:

http://api.ipstack.com/{IP}?access_key=YOUR_ACCESS_KEY&output=json&legacy=1

where YOUR_ACCESS_KEY should be replaced with the key that you get after registering.

Note that we do not expect that we need to make any code changes in BASE due to this. Fixing the base.config file should work also with older BASE version. (Turns out that a BASE update is needed, see comment:1)

Unfortunately, the new service will not work with the existing BASE code. The problem is that BASE will only accept the answer if the response contains a line:

Content-Type: application/json

The new service sends:

Content-Type: application/json; Charset=UTF-8

Thus, BASE also need an update in order to accept the answer from the new service.
