Fix windowChange not refreshing valid media queries

* css/cascade: copy stylesheet in applyMediaQuery (so that changes
  are reverted on re-style)
* buffer: clear prevstyled in windowChange (to avoid using cached
  results from previous cascading passes); set window.attrs
* pager: avoid windowChange if new attrs are identical to the old ones
