Need to have reviews under /$PROJECT/$review_number

Need to have reviews under /$PROJECT/$review_number

If all the reviews are just review/$review_number
I dont have sufficent information to search reviews per project
this is needed for the new search tool

If this change is merged I will need to delete everything under /review/
this will lose current review artifacts, but allow future ones to be
searchable in the upcomming interface

Please comment if you can think of a better way to do this.
note: at some past point reviews were in their project folder.
