Pay Bills: Ability to add an attachment

Hello, Improvement request - simply adding more attachment options to other windows.

I would like to be able to attach the Supplier Statements to the Bill Payment to keep copies of the statements filed.

I would also like to be able to attach the Bank Statements in the Reconcile Window. That way the accountant has instant access to them when required.

I would also like to be able to attach files to Journal Transactions. Sometimes you need to add the details/correspondence/authorisation etc. to a Journal Transaction to show why the adjustment was made. Or for the accountant to show the workings for entries. 

Should be fairly simple as the coding would already be written for the Enter Purchases Window.

Thanks.
