Patch: add double click behaviour to account list in invoice payment dialog

[Geert Janssens]

Hi,

The attached patch adds a double click action to the account list in the 
invoice payment dialog.
The behaviour is as follows:
* if the account that is being double clicked has child accounts, the children 
are expanded
* otherwise the account being double clicked on is selected and the dialog 
window is closed.

I have more or less copied this behaviour from the commodities dialog, as I 
find it a very useful feature. It saves me a lot of mouse gestures when paying 
invoices.
