Staticweb shortcut object 404s

Right now static web checks to see if it should handle a
request and if it decides that it shouldn't, in all cases,
it lets the request pass through the pipeline normally.
After this change on "x-web-mode: t" obj requests where
staticweb is not setup and an object 404s it will just
return the 404 instead of letting the app send a duplicate
request to the object servers.

DiskFile logger argument is not a keyword

This was broke somewhere pre-1.9.1.
