feat(dialog): add a config option for passing in data
Adds the ability to pass in data to a dialog via the `data` property. While this was previously possible through the `dialogRef.componentInstance.someUserSuppliedProperty`, it wasn't the most intuitive. The new approach looks like this: ``` dialog.open(SomeDialog, { data: { hello: 'world' } }); class SometDialog { constructor(data: MdDialogData) { console.log(data['hello']); } } ``` Fixes angular#2181.
