Print docs in both Color & Black & White

[toledoal]

Currently when we want to print the documentation we get a black & white theme. That makes sense for common printing. But some people may want to print in full color.

We have two problems.

1. The UI mechanism to allow the users to print both version.

a) We could have a general settings button to establish the default version for printing. (Not very ux friendly)
b) Have two buttons to print (one for color and one for B&W)
c) Have a dropdown in the print button to offer the options (Color, B&W)

2. If we print in color the contrast and color of the "blocks" might be difficult to read in paper. Like for example pink box with white font next to a red box.

a) Define a set of print colors for the blocks and apply a color CSS sheet
b) Define a set of print safe colors to use across the app so we can use those everywhere.
