Getting started with D - Phobos documentation sucks

[JN]

While we're speaking about docs improvement, I believe there is 
one more thing that could use a fix - clickable identifiers. I 
don't know how much of an effort it would require, so consider it 
a wishlist, but for stuff like:

static @property @safe TickDuration currAppTick();

TickDuration should be a clickable link leading to 
core.time.TickDuration class docs.

Example: 
http://docs.oracle.com/javase/1.4.2/docs/api/javax/swing/Icon.html#paintIcon(java.awt.Component, 
java.awt.Graphics, int, int)

notice how Component and Graphics are clickable so you can 
instantly jump to their relevant declarations. This feature along 
with the abovementioned improvements would probably make the 
documentation a useful and intuitive tool.
