Print remote info and verify status lines through internal/ui (closes #410)

The status and progress lines of `remote info` and `snapshot verify`
(shallow and deep) now use the `internal/ui` Begin, Complete and
Progress methods, so they carry its marker and, on a terminal, color.
The reports themselves stay plain on stdout.
