In this commit we introduce first and last indices for the
tranasctions returned which can be used to seek for further
transactions in a pagination style.

This commit fixes the display of the amount when
selecting utxos for the sendcoins command and
combining it with the `-sweepall` flag. Prior this
would show the full balance of the wallet. Now it
shows the total amount of the selected utxos.
We want to export some of our CLI code to re-use in other projects. But
in Golang you cannot import code from a `main` package.
So we need to move the actual code into its own package and only have
the `func main()` in the `main` package.
