[chef] Chef Installation Documents Revamped

[Joshua Timberman <joshua@opscode.com>]

All,

I have revamped and revised much of the getting started and  
installation documentation.   The biggest change is the main  
installation page, where I pushed the Ubuntu/Debian specifics out to  
new pages.

Installing with RubyGems - this page generically describes the process  
to install RubyGems from source, add the Opscode gem source, and  
install Chef and Ohai. It's actually a metapage, there's a "RubyGems  
Instructions Excerpt" page that contains a hidden excerpt used by  
several other pages so we have one source and can have DRY docs.

Configuring Chef Server and Clients - this page is where all the "chef  
solo bootstrap" information lives now. It's still relatively Ubuntu/ 
Debian and CentOS specific, but at least it isn't on the main  
Installation page confusing new users.

On the main installation page, there's an Install Requirements section  
that describes how to install Chef's requirements on a per-platform  
basis, including how to install Ruby or how to install Chef via  
platform specific packages instead of RubyGems.
