493dbde666b73097848a5a4c7d10ee1ad7cfeab2 gui: cleanup the "amount left to select" calculation (Antoine Poinsot)
Pull request description:
It don't think it was blatantly wrong, but neither was it entirely correct. And it was seriously lacking comments explaining what was going on for such a tricky calculation.
In order to make sure it's correct, and make this more code more maintainable (and readable to future contributors), clean it up by using a more obviously-correct approach: a transaction template that is filled with inputs depending on the coins that were selected.
I DID NOT TEST IT!
