Checkbox does what you would expect. Press tab from the amount field to get there.
It's unchecked by default.
When launched with `-addresstype=bech32` it's checked by default. When launched with `-addresstype=legacy` it unchecked and disabled.
The change in `receivecoinsdialog.ui` is smaller than it looks, due to the way git handles XML diffs. I had to add a horizontal spacer to make it look decent, see https://github.com/bitcoin/bitcoin/issues/11950#issuecomment-352870909. This causes column numbers to change in the rest of the grid.
I recommend testing on at least one other OS than OSX to be on the safe side.
