Ensuring callback provided to Shapefile constructor is executed even if a dbf file is not provided
Fixed support for Point datasets

While some support existed, an attempt was being
made to create an unnecessary(?) bounding box for
each point feature. Also swapped access of the x,y
coordinates from record.geometry.x|y to record.x|y.
Add jsRoot constructor option

Workers were being constructed with a hardcoded path of
'shapefile.js'. The new jsRoot option can be used to
specify an alternate location. For example:

  shapefile = new Shapefile({
      shp: "testdata/world.shp",
      dbf: "testdata/world.dbf",
      jsRoot: '/js-shapefile-to-geojson/'
  }, function(data) ...
