fix for bug 834593 Dividers on search pages do not match mocks
Move assertQuerySetEqual to the base test case
remove -o- prefixes lol
Remove more spurious prefixes

Notes:
* -webkit-box-sizing is only for Blackberry Browser LOL
* transform-origin is surprisingly poorly supported.
* appearance isn't even proposed, don't include it.
* The marketplace is Aurora (FX 20), so Firefox 15 and below are a
small fraction of a percent of our (unsupported!) user base. Lots
of -moz- can go away.
