Tomaz Canabrava bb59202812 Made the TableViews share a bit of code, code cleanup. 
Made the tableviews share a bit of code, and code cleanup.
The tableviews for Cylinders, Weigth and Dive Planner Points
now shares the CSS and I also implemented the save / load
methods for the dive planner points, so the functionality
is mostly done on the vieualization side. - since we are
now using three tables maybe it's a better idea to create
one class SubSurfaceTable that knows how to handle saving
/ loading of the columns... TODO for the future. ;)
