[ADD] account_journal_general_sequence: account move entry sequence

Under some legislations, account moves must follow a single sequence. Since Odoo removed this sequence number in recent versions, this information was lost.

With this module, you can force your account moves to follow a separate sequence. The sequence is automatic when a move is posted. Includes a wizard to reorder those numbers in the sequence.
