Zoosk modifications

The most significant of these changes is in where during the apache processing timeline this resolution happens.  I think that where I've placed it is more appropriate.  It allows mod_rewrite and other such rules to work as expected.  The previous location caused a number of problems.

I also downgraded the severity of file not found errors, since we get a number of incoming requests that indeed do not have a file.  That's fine, and those will be handled with 404s or appropriate responses.
