Feature/color

[andy176631]

Hi all,
I developed a feature that providing table with color output. It allow to assign the color/attribute for the text in each cell. What I mainly add to project are:

1. Color/attribute class in skb-java-interface
2. Generate a color configuration table in ascciitable
3. In ascii-utf-themes, append ANSI code to the text at last step before frame transfers to array of string.

Usage example:

  final AsciiTable at = new AsciiTable();    
  at.addRule();		
  AT_Row r0 = at.addRow("c_0_0","c_0_1", "c_0_2");
  r0.getCells().get(0).getContext().setTextFgColor(FgColor.GREEN);
  r0.getCells().get(1).getContext().setTextBgColor(BgColor.GREEN);
  r0.getCells().get(2).getContext().setTextAttribute(Attribute.BOLD);
  at.addRule();	 
  AT_Row r1 = at.addRow("c_1_0", "c_1_1", "c_1_2");
  r1.getCells().get(0).getContext().setTextFgColor(FgColor.RED);
  r1.getCells().get(2).getContext().setTextBgColor(BgColor.RED);
  at.addRule();
  at.setTextAlignment(TextAlignment.CENTER);	
  System.out.println(at.render());

Output:

Is it easy to build this change for myself? I see there are PR across three projects..
