Merge bitcoin-core/gui#719: Remove confusing "Dust" label from coincontrol / sendcoins dialog 
a582b4141f gui: send, left alignment for "bytes" and "change" label (furszy)
210ef1e980 qt: remove confusing "Dust" label from coincontrol / sendcoins dialog (Sebastian Falbesoner)

Pull request description:

  In contrast to to all other labels on the coin selection dialog, the displayed dust information has nothing to do with the selected coins. All that this label shows is whether at least one of the _outputs_ qualify as dust, but the outputs are set in a different dialog. (Even worse, the dust check is currently simply wrong because it only looks at an output's nValue and just assumes a P2PKH script size.)

  As the label clearly doesn't help the user and is, quite the contrary, rather increasing confusion/misguidance, it seems sensible to remove it. The label from the sendcoins dialog is also removed with the same rationale. Additionally, the "bytes" and "change" labels are aligned to the left (second commit).

  Closes https://github.com/bitcoin-core/gui/issues/699.
