>Description:
Improve the readability of the Table of Contents of the FreeBSD Handbook by applying colours to links.

Until now the handbook has had no style on links, resulting in the default bright blue / purple link colours.

Apply style to make the colours a little less jaring and easier to read, also makes the page not look like it is from 1994.


Borrowed the colour codes from http://en.wikipedia.org/wiki/Help:Link_color since these seem to be what people will expect
