More verbose when updating templates

[Jeff Escalante]

Updating templates can take a second, as noted in other issues. To make to make it clear that sprout isn't just hanging, there should be more verbose output when sprout is updating a template. As a bonus, it should note if the template is up to date or if it updated to a new version 😀
