Retry button in offline menu

[davidmayr]

When the launcher asks you to put in a name for offline play (I get that if I leave the launcher open for too long) just please add a retry button. It would try to reauthenticate the profile and start with online play.

Would be very helpful!

This would also be helpful for anyone who may launch the launcher while not on a network, and then later connects.

Yeah can we move this to one of the following issues: #520
or #592 or #920
This looks like a possible solution for them(the best would be to not have any user input and work on its own).
