Ember and Boolean Attributes broken in 0.9.2

[John Ratcliff]

#302 introduced a regression where boolean attributes are now quoted and don't always work

Ember will coerce boolean attributes:

multiple={{ trueValue }} => multiple
multiple={{ falseValue }} => nil
multiple={{ blankValue }} => nil

However, after these changes the falseValue scenario will evaluate to true.

Ember issue to see if this is intended behavior
