[Blink] Google contacts

[Dan Pascu]

Google contacts should now work without restrictions.

Starting with 11th of April Google finally fixed the quota issue for the 
People API (not because of our request from 4 months ago, which is still 
unanswered to this day, but because they just changed the People API 
policy and removed any limit on the number of daily application requests).

For those unaware of the issue, in the past 4 months since we switched 
to the People API and the new OAuth2 authentication, Google contacts 
would only work for a few hours per day until a very low (max 10000 
daily requests per application, i.e. shared by all Blink users) quota 
was reached.
