Prolog 4.1.0.51

Have made the following updates:

• In the graphics plot we have added a plotting fudge scale to get printouts exactly right on printers. If plotted sale for example is coming out at 98% then add in a factor of 1.0204 (1/0.98) Otherwise leave at 1.000
• Minex lith and pck files were being created with the .prolog still in the file name.
• If you specified that you were using a border and border drawing was not found not printout was created. The border is now ignored.
• After a "Save" you may have seen  tags in the data. They were removed when saving. Now fixed.
