Account subvention

Add a new model to manage subventions. If a subvencion and a percentage is added to the customer, when an invoice is generated, these fields will be filled automatically in the lines. Once an invoice with a subvention is validated, the account move line will be divided so that one of them will have the percentage that the subvencion must pay and it will be subtracted from the total amount to be paid by the customer. From the account move lines of the subventions view you can reconcile the account move lines automatically from a button. In addition, there is a cron to perform the reconciliation of all the account move lines associated with any subvencion automatically.

NOTE: In order for the account move lines to be reconciled, the associated journals must have the 'Default Debit Account' and 'Default Credit Account' fields filled out.
