Re: [css-flexbox] Syntax for maximum support

One correction: there's no need to use "-moz-" prefixing for any of the
current-flexbox keywords & property-names.

Mozilla has shifted away from vendor-prefixing, for a variety of
reasons.  Instead, we're shipping work-in-progress CSS features
unprefixed, but behind about:config prefs (which are disabled by default
until the spec and implementation are sufficiently stable & complete).

So: the "new" flexbox spec's keywords are all unprefixed in Mozilla
code, though they're still disabled by default in our release builds.
(But it should be enabled by default soon.[1])

(Technically, we did actually ship one old release (Firefox 18) with
*both* the pref and with prefixed flexbox keywords & properties -- but
the number of users on that out-of-date release who've refused/disabled
automatic updates and who've *also* manually toggled the flexbox-support
pref should be extremely low -- likely zero.  That's the set of users
you'd be targeting with -moz-prefixed new-flexbox keywords markup, and
IMHO it's not worth it. :))
