Bugs fixes or improvements:
   *  Rearranged the project settings dialog, it now has tabs for different data and settings

   *  Show/hide layers in the linesplan
   *  Save a preview of the model in the file (used for browsing designs at the FREE!ship website)

      from the project settings or the actual waterline dimensions

      mousebutton (or mousewheel) pressed

      pressing + or -. Click the panel saying "Incr. distance" on the statusbar to manually set
      the distance.
   *  Added the following waterplane properties to the hydrostatics: waterplane area, coeff., LCF,
      entrance angle and Trv/long. moment of inertia

   *  Added sectional area info to design hydrostatics
   *  Project selected points on a straight line segment

Bugs fixes or improvements:
   *  Fixed bug in offsets import from round bottomed hulls that ignored the metric/imperial
      settings in the file
   *  Prevent the program from zooming out on the model when undo is used
   *  When layers are turned on/off, viewports that have been zoomed in or out are simply redrawn,
      others viewports are zoomed out to the extents of the entire model
   *  Severe error occurring when an edge was collapsed with two faces attached with inconsistent
      normal directions
   *  Fixed locked points that where not scaled when the project units was changed to metric/imperal
      are correctly processed
   *  Corrected an error in the routine were imperial distances were translated into a text containing
      the number of feet and fractional inches. This error occurred when the value was negative but larger
      the -1.0 foot. In those cases the negative sign was omitted.
