[Shapelib] Removal of PROJ dependency (and functionality) in shapelib ?

[Jeff McKenna]

No real objection here.  Although I may be one of the few who distribute 
the latest Shapelib and contrib utilities, on Windows (I recently made 
sure to package these for the MS4W-version 4 beta).  I believe the 
contrib utilities are still useful to people.  -jeff
