Modify about:flags to support switches with values.

about:flags right now doesn't support switches like "--foo=bar".  It only handles
simple switches like "--quux".  The prerender feature has a few options, and to avoid
confusing contradictory mixes of simple switches, we want to use valued switches.  But for
that, we'll need lab support.
