NY: NY 417 Point Errors From Addison to Salamanca

[Markkos1992]

1.  CR432 should actually be CR119.
2.  Obvious off-center points (CR85, PotRd, WilRd, CR12, McKeeRd, NY275 - though most are at least slightly off-centered)
3.  The point for BackRd should be for Sherwood St (based on Steuben County GIS).
4.  AndRd should be AndSt.  (verified via GIS)
5.  BriBroRd should be CR18.  I found on GIS that the road name could be Petrolia Rd, but the CR 18 designation is a certainty.
6.  If possible, the Desoto Ln point should be replaced with one at Gargoyle Rd.  The latter at least has a signal and leads to a park.

1. Changed.
2. Went thru the file and recentered points as needed. I did NY275 since you mentioned it here, but otherwise left points with intersecting routes alone; I didn't want to have to edit a bunch more files. Mission creep...
3, 4, 5. Changed.
6. I left this one in place, as it's in use.

While I was in the editor, I also replaced a number of hidden shaping points with visible intersection points where feasible.
