Add support for reprojection of vector formats when loading data. This allows

for the definition of a 'projection' option on a layer. IF this projection 
object exists, it will be used to create the format's internal/external 
projection options, making it such that any data loaded will be reprojected 
to the map's projection automatically. r=pagameba (Closes #1273, #1225, #1269)
