Rename "Delegate" to "Synthetic"

This is just a simple rename of the event classes to `SyntheticEvent`. I've also updated the constructor arguments to be more correct:

 - `dispatchConfig`: Data used by the plugin system for dispatching the event, for example: `{registrationName: 'onClick'}`
 - `dispatchMarker`: An identifying marker used to describe where the event is occuring, for example: `.reactRoot[0]`
