Decide whether to send statistics to Esmska server or not. We don't want to send stats too often so that the server is not overloaded. The current decision algorithm:

• If this is the first time Esmska was ever started, don't send anything.
• If this is the first time Esmska was started in current month, always send.
• If today is 20th or earlier day in the current month, send stats at maximum once per 5 days (check last submission date and decide).
• If today is 21th or later day in the current month, send stats at maximum once per 3 days (check last submission date and decide).

Returns:
