Prusa i3 MK 2.5 endstop

I noticed that the new x axis end in the Original Prusa i3 mk3 has several key advantages like adjustable tension, an offset on the pulley, tolerance made for PET-G, and bearing retaining lips that are neat. I figured since I was upgrading to the mk 2.5 I might as well attempt to upgrade the entire x axis, including getting the mk3 x axis to work on the mk2.
