Account Invoice Select for Payment

This module adds a simple marking system on customer and vendor invoices so you can prepare a payment run without leaving the invoice list.

• In the invoice list you get a new toggle column called "To Pay". It only appears for invoices that are not paid yet or only partly paid, so fully paid invoices cannot be marked.
• You can switch the mark on or off for one or several invoices at once; the module flips the mark for the records you selected.
• In the invoice search filters you get two new options: "Selected for payment" and "Not selected for payment", so you can quickly list only the invoices you have marked or only the ones you have not.
• When you register a payment on invoices that were marked, the mark is cleared automatically, so the selection does not stay behind after payment.

It works on the account.move model, which is the model behind invoices, and it only extends the existing invoice list view and invoice search filters. No new menus or reports are added.
