[CentOS-docs] initial page for Centos 6 FAQ

[Manuel Wolfshant]

Hello

     In preparation of the soon-to-arrive Centos 6, I have created the 
http://wiki.centos.org/FAQ/CentOS6 page and added to it the explanation 
for the disappearance of boot.iso.
     As usual, please help in keeping the documentation updated / 
corrected / etc .


     Manuel

PS: I did not add the reference to new page in the main FAQ page, I am 
waiting for the official release of the distro.
