Changes

• Fixed table drawing code so column footers won't flicker (as much)
• Removed all the messy tests for gridlines, replaced by adding style information for borders: border, border_color, border_spacing
• Added x_margin, y_margin to Flv_Style for programmable cell margins.
• Added dead_space_color to handle non-painted region.
• Fixed several Flv_Style_List bugs
• Changed draw_row, draw_cell to use &X, &Y, &W, &H so the default functions can get you all set-up (minus the alignment) to draw.
• Added compact to Flv_Style_List to release any unused styles.
• Fixed Column & Row Header/Footer styles to only be overridable at the cell level.
• Updated testtable2 to show more features.
• Fixed bug in col_width(size,column)
