light editing of variable precedence list wording

QA had asked me a while ago to clean up the way the precedence list for 1.x was worded,
as the intro from the list started with "then comes", as if something should preceed
it. The comments from OxABAB were not helpful themselves, but his issue reminded me that
this was on my to do list to make a little cleaner and clearer.  Edits made to remove the
"then comes" intros for each list line, to help with clarity.

 Basically, anything that goes into "role defaults" (the defaults folder inside the role) is the most malleable and easily overridden. Anything in the vars directory of the role overrides previous versions of that variable in namespace.  The idea here to follow is that the more explicit you get in scope, the more precedence it takes with command line ``-e`` extra vars always winning.  Host and/or inventory variables can win over role defaults, but not explicit includes like the vars directory or an ``include_vars`` task.
