New color palette

The new color palette is now in use! As shown above, click on any color blobs in configuration panel to invoke the palette. It sits in a glossy modern-looking transparent plate, contains a display of lovely colors (with their even more lovely names printed on them), and .... a gradient slider!

To use it is simple: pick up a color by clicking on any named block and that color is chosen for whatever purpose. You can go further to select a lighter/darker version of that color by dragging the slider (or clicking on anywhere on the gradient stripe).

Palette colors were selected from here: http://www.w3schools.com/html/html_colornames.asp

The new palette is really a complete upgrade to its predecessor. It displays color names, which is helpful for vision-impaired users so they know what they are looking at. And it supports much wider spectrum to choose from. Looking good is important!
