Suggestion: Use Tango color palette for PSPP output file

[Bastián Díaz]

As an improvement on the visualization of the output data for PSPP, I recommend 
using the Tango color palette. 
(http://tango.freedesktop.org/Tango_Icon_Theme_Guidelines)

It is the same color palette I used for the new artwork for PSPP and the color 
palette is used by many other OpenSource projects.

Examples of use:

→ When you open an HTML file from a web browser (Firefox), the default style 
displays a gray background in the row/column title 
(https://dl.dropboxusercontent.com/u/5204736/PSPP_Output_Firefoxview.png). This 
seems very dark gray. 
I recommend: #eeeeec or #d3d7cf

→ Colors for plots generated by "plotutils" in PSPP.

→ Colors for syntax highlighting.

This idea stems that many PSPP users working in academic or professionalarea, 
and any small improvement in the visualization of the output data can be very 
welcome. PSPP also gives coherence and elegance in its design.
