[ale] Centos 7 installer

[Damon L. Chesser]

yeah, I have to put on my curmudgeon hat here.  what was wrong with a 
linear install?  This spoke and wheel thing is for the birds, especially 
when it comes to complex hard drive layouts, like multi mdadmin drives 
and LVM + encryption.  I am sometimes surprised at how well it ferrets 
out my intent, but if it is wrong, it gets damn hard to fix it.  Their 
time would be better spent by designing a UI completly different from an 
UI that just gets out of your way and lets you get things done, no 
wait:  Never mind.
