This uses the strategy to create one transaction per utxo instead of one
per address which makes this module actually provide some usefullness to
such wallets.
This shows the amount of coins stored on a single address, which we
sweep in one transction by default for privacy reasons.
This adds the ability of the user to specify how many outputs a single
transaction should have when we create it.
Instead of pre-allocation, this moves it to just before we actually
broadcast.
This solves a possible failure of detecting target funds in case the
number of transactions is larger than the gap and the user sends only
one or two of the later once instead of all.
This is probably a good first milestone, the UX is pretty decent
and the wanted functionality is there.
Various todo's are still there which mostly of the cleanup type.
