snac: update to 2.66. Changes:

As many users have asked for it, there is now an option to make the
number of followed and following accounts public (still disabled by
default). These are only the numbers; the lists themselves are never
published.

Some fixes to blocked instances code (posts from them were
sometimes shown).

Fixed non-appearing buttons `Approve` and `Discard` if the account
requesting a follow were being followed.
