New star graphics for default state
New option: defaultState - Enable a default state for the stars
New option: defaultShow - Whether to show the default state when the user
is mousing over the stars
New option: starDefault - The icon to use for the default state when
defaultState is true
Added "stateChanged" value to that.self.data to keep track of whether a
score has been selected
Moved init method's "that.data" above method calls to ensure those values
are available on further method calls to subsequent methods in init (e.g.
_createStars, _createScore, _apply)
Added ignoreState parameter to _fill method to allow mouse over events to
trigger "on" state when defaultState is enabled
Updated demo documenation and examples for new defaultState option
