Subject: Fix some crashes Make double clicking on the header dividers
 automatically

Fix some crashes
Make double clicking on the header dividers automatically size the header
to it's best fit.
When dragging onto the header check the dragged item is a header object.
Check the column is resizeable before setting the cursor to <->
Use the font and themes to draw the table and items.
