Update print/p5-PostScript-MailLabels to version 2.10.  Changes from
version 1.01 include:

* Added parameters for 5167 Avery (tm) stock. Also added many new
  Avery (tm) parameters.

* Added new parameter set 'freetype', to allow the user to place a text
  string anywhere they want. Particular use is for numbering the pages.

* Code now escapes special PostScript characters (){}[]<>/% in the
  input so that they will print properly and not crash the PS interpreter.

* Changed to honor user-defined number of columns.

* Added y_gap to Avery(tm) labels
* Updated calibration plot in BasicData to arbitrary paper size

* Added all of the component and label definition stuff.

* Added pagesize so that various paper sizes are actually handled correctly.
