Master account sequence management pvy

It is used for 2 purposes : At journal creation, if checked, sequences are automatically created for all the already created fiscal years. Also, when creating a fiscal year, in the sequence restart wizard, journals having the restart_sequence field set to True are added by default to the many2many field of journals whose sequence are to be restarted. This is done in case the user wants to restart the sequences of the same journal every year, in which case the user will only need to click "restart" without having to further add or remove journals from the list.
