Title: Allow WordArray to support a minimum array size

Sometimes it is preferred to use an array for a small number of strings
and only force the use of %w %W when the item count it large. This
allows the WordArray style to only complain if the number of string
elements are over the set minimum.

Not entirely sure about the setting name. MinSize seems fitting.
