Title: View lookup should return something at least

Even if the path doesn't exist it's better for the lookup
method to return the last path checked. Without a return
value, if one attempts to render a path that doesn't
exist one gets "TypeError: Bad argument" because the
first param for fs.readFile is undefined. If the path is
returned one gets the more helpful "Error: ENOENT, no
such file or directory" along with the string for the
path.
