*bugfixed: the partners displayed on the report wasn't good (tiny at work were written every where)

*when the wizard is run, all the invoices receive now a value for latest followup date and followup level (accordingly to the level of the account_move_line)
*the email sending is implemented. The email is structured as the report
*added a column for maturity date, in Financial Mngt\Periodical Processing\send followup\all receivable
*in the many2many of the wizard in Financial Mngt\Periodical Processing\send followup, added a filter per account type == receivable
