No ability to set the `verbose`

[phillip-haydon]

Also, the parameter has been changed from verbose to verbosity

Verbosity Display this amount of details in the output: normal, quiet, detailed.

Usage is like:

-verbosity quiet

Will fix the warning:

[17:01:24][pack] WARNING: Option 'Verbose' has been deprecated. Use 'Verbosity' instead.

And allow me to turn it off since I don't actually care what files were added to my package for dev builds.
