[css-cascade] unwinding all: property

Somehow it would appear that I was absent or asleep during earlier
discussions on this, so apologies for that, but I have an issue with our
current incarnation of the all property values.

Essentially it boils down to this:  I would be willing to wager my last
dollar that the vast majority of authors do not understand how the browser
arrives at how an HTML page is rendered with no author stylesheets.
Currently many friends and people that I talk to are dismayed or surprised
by the behavior having expected it to do something more "default" like:

all: user-agent;

and reset back to -that- behavior.  If suddenly the contents of script or
style tags is displayed, or blockquotes just look like regular inline text,
that seems to be upside down on the priority of constituencies.  Currently
it's up to them to recreate and define what would have been an initially
sane group of styles and that seems just wrong.
