[Wishlist] Add support for transaction linked documents

[Freddo3000]

Gnucash has support for associating external files with transactions, which is useful for scanning receipts, invoices, and other records. The problem is that users can only do so when they have access to a computer, and requires a consistent file structure or separate webserver.

It is on just that separate webserver part where I think this project could be used, allowing the user to upload files while on the run which can be accessed at as something such as http://gnucash-web.etc/files/myreceipt.png, and implementing this as an option when creating a transaction. This would allow users to digitize receipts using their phone and unless they have a reason to hold on to the physical receipt, discard it.
