Why do you need to export StyleRule from core? this doesn't belong outside core

[rune, 2015/09/10 13:54:50]

Because RuleFeatureSetTest.cpp needs access to StyleRule and unit tests are in a
different component than the rest of Blink, I think. Which makes the CORE_EXPORT
thing pretty broken as you in an ideal world would unit test all your classes,
effectively making all your classes CORE_EXPORT.
