CDS 2.5.27

1. When doing a point listing you can now specify accuracy (number of decimal points) for chainage and offset.
2. When sending strings to a DWG the color and linetype was not always coming across. Would happen when string had color and linetype set differently to the layer.
3. You can now specify a transition spiral as part of the string definition. For example when doing a string entry it could be specified as    1,s2,s3,+4,s5,s6,7    This defines as a straight from 1 to 2, a transition spiral from 2 to 3, around curve at center 4 to point 5, a transition spiral to 6 and going to straight at 7. More details coming shortly.
