Title: Revert "Transform dasherized properties to camelized in {{view}}."

This reverts commit c7c05f474edd7d27350b0f0542c4a641558d3155.

I still feel that #5398 was the correct direction, but there are a few places in our current API that are broken by this change. Two examples are the use of actions (`focus-out`, `focus-in`, etc) and view events (`focusOut`, `focusIn`, etc). If this change were left in place the view event handler function is clobbered by the camelized action name.
