Events without type

It is not required to supply a type field in mozContentEvent. There are two file sending mozContentEvent with id as its field to tell gecko what's going on: identity.js and payment.js. All of them returns values to specific mozChromeEvents.

identity.js	id-dialog-done	dispatch event when a "id-dialog-done" mozChromeEvent received. The trusted UI will be closed if it is opened with id-dialog-open.
