Change Closure type for goog.ui.ComboBoxItem's opt_data constructor parameter to match that of the base class's (goog.ui.MenuItem's) opt_model parameter which receives it.  There's no reason for it to be the more restrictive Object, thus denying use of primitives such as "string" without generating a type warning such as this:

actual parameter 2 of goog.ui.ComboBoxItem does not match formal parameter
found   : string
required: (Object|null|undefined)

RELNOTES: Type of goog.ui.ComboBoxItem's opt_data changed from {Object=} to {*=} to match type of goog.ui.MenuItem's opt_model.
