There is a wired thing going on with Dart's DOM facade and the innerHtml property:

• DOM(hasProperty, 'innerHtml') => false
• DOM(hasProperty, 'innerHTML') => true

but:

• reflector.setter('innerHtml') => exists
• reflector.setter('innerHTML') => null

which basically means that we can't use the same name to test for a property name and lookup a setter in Dart....

I'm going to special-case this property for now to unblock #619 but if any person more familiar with Dart could give me a hand with this one, it would be awesome.
