Make Ocelot not add forward slash to downstream url (#158)

* removed code where we add a trailing slash as this means if we request /1.txt/ instead of /1.txt then some servers will not return the resource at /1.txt. After reading up it seems if you dont have a trailing slash then its a file, if you do then its a resource

* test for 145

* removed unused code

* fix broken build..my bad
