Subject: Update of Maplink. New version: 0.3a

Version 0.3a
------------
- A lot of bug fixes
- Totally new geometry library (libs/phpgeometry_class.php). All geometry are now objects.
- Support for editing of island polygon (donuts), still not creation of them, through the new geometry library.
- It is now possible to zoom and pan while redlining lines and polygons for editing, quering and measuring. This is a new experimental feature and it may be buggy.
- Deleting and cloning of "nodes" while redlining. Double click no node elements for delete or clone.
- VMS-abstract text is now encoded server side and decoded client side and strange chars should no longer cause an error.
- New pdf map generator - thanks to the Fpdf project.
- Simpler editing dialog.
- Scripts for viewing and updating attribute data with tentative client side validation. It is now possible to edit the attributes of a selected feature.
- Area calculation in client - at last.
- Serverside url encoding and decoding of xml, so content with html and urls not will cause any problems in the output html table. Use the $postGisQueryUrlEncode[MYLAYER]="FIELD" variable in conf. file.
