Snackbar / Toast Please add support for CSS Class

[naveedahmed1]

Snackbars are great to provide brief feedback about an operation through a message at the bottom of the screen.

It would be really nice if we could also add css class for a Snackbar. For example if the operation failed to complete we could display it in a different color (probably red) whereas in case of success, we could apply different styling (probably a snackbar in green color).
