t-raw is used to inject safe-ified JSON into a script tag.
The scriptsafe json pseudo-module takes care of that, so remove
explicit escaping and use a script-safe JSON dump.
As of June 22 2016, the use of API key is required to access the
following:
- Google Maps JavaScript API
- Google Static Maps API
- Google Street View Image API

For domains accessing the API before June 22, it will still work without
an API key. Since Google advises to use the API key, we hide the Maps if
no API key is defined.
