Implement day off window

[Zocker1999NET]

After a day is gone the webpage shows you the dailes you may have missed to tick off, however opening your client does suppress this window and the opportunity to tick off dailes done. This can destroy streaks and even kill you (in Habitica).

I think about a menu right before you get the normal prompt showing the missed dailes where you then can select which of them you have done and then continue to the next day.

In connection to the feature of #6, by default the client should exit with an error code not doing what was requested until the dailes of the last day were tick off.

An additional command line parameter like -f/--force should enable the behavior this client has right now, ignoring this opportunity.
