This stores the time of a transaction in the store of the wallet, and
indeed sets it when it is added to the wallet first time.
For instance when we create it or when the tx is first sent to us at
initial broadcast.
We add some logic to the model in order to put a bit more effort into
finding times of a transaction that did not get mined and (before this
code) did not get its time of creation set. Mostly this is about
rejected transactions. And there we guestimate the time instead.
Slowly the amount of cpp sources has been growing to the point
where its just too much to store in the root of the project.
I think they are more happy in a subdir as well, getting an elevated
position for themselves.
