Installation Guide (minor) error

I think u should edit first post where it says
"1. Keep in mind that SMF is still in beta.  "

I think when people read get confused.
I suppose this was written when it was still in beta version. Now SMF 1.0.x is stable enough to clear this line.

SMF was still in beta at the time that was written, but I don't know why that line never got removed. I'll fix it.
