Standard creation of installment invoices within a project.

Many construction companies work with term invoices, often they also have an established method in this.

We want to offer them the possibility that they can set in settings->invoices how many term invoices they want to create by default per project, with automatic percentages / VAT linked to each term invoice.

Each new project is then automatically created with the set number of term invoices to which the percentages / VAT are linked. These invoices will automatically come in a term sheet within the project.

This saves time per project creating new term invoices, and increases user convenience.

When dividing the installments, it should not be possible to exceed the project sum. This should be clearly indicated.
