Cleaning up Deface overrides

Two commits here. I opted to apply these to the 1.0 branch because that branch did not yet get some namespacing that the master branch already contains.

This commit replacing hard view overrides with Deface customizations should also be applied to the master branch, since it hasn't been done yet: https://github.com/patrickmcelwee/spree_wholesale/commit/e15d9be788c30189cbaca26b037252af2b1c8962

Let me know if you want me to put together that pull request.

This commit provides namespacing just for 1.0: https://github.com/patrickmcelwee/spree_wholesale/commit/9dcda7f1f0a8a80ee2f75381dd4ca72312dde783
