Google search not working because of API changes

[DSchndr]

The old Google websearch API is deprecated.
Because of this the bot throws
Body: /search cat
Traceback (most recent call last):
File ".../src/router.py", line 76, in handle_callback
data = callback(message, match)
File ".../src/views/google.py", line 29, in google_search
page_url = urllib.unquote(req.json()["responseData"]["results"][0]["url"])
TypeError: 'NoneType' object has no attribute 'getitem'
at me when i try to search something.

An fix would be to modify the code to fit the custom search API.
