Subject: [PATCH] Catch keyboard interrupt when opening journal (#476)

If the journal is encrypted, jrnl asks for a password using the
getpass.getpass function. If user presses the keyboard interrupt (e.g.
ctrl+c) during the password prompt, jrnl crashes and prints a stack
trace. This however is not very user friendly.

This commit adds a check for KeyboardInterrupt Exception and prints a
message whenever this exception occurs and exits. Stack is no longer
printed.

Fixes #450
