Support custom views on snackbars
Split the existing Snackbar class into two - the base class
with the common functionality for the lifecycle management
and action, and the extending class that "adds" a text message.
The extending class maintains the existing API surface.
This CL has sample code for a custom snackbar in SupportDesignDemo,
as well as unit tests in CustomSnackbarTest class.
