ANN: Build Guide 2.0.1

[Dennis Leeuw]

Hi all,

There is an updated 2.0.x version of the GNUstep Build Guide for Unix 
systems: http://gnustep.made-it.com/BuildGuide/index.html

Changes
-------
Removed all GNUSTEP_*_ROOT occurrences

Chopped the document into 3 parts (still a single document) according to 
content:
        I. about GNUstep
        II. Building GNUstep
        III. Configuring GNUstep
This gave me the opportunity to better introduce GNUstep and the 
different parts. And to explain the domain part before building.

A couple of chapters, sections and paragraphs received a different place 
within the document. Hope this makes it a better document.

Happy Stepping,

Dennis
