Allow to be closed with a click anywhere in the toast

[abenhamdine]

Currently, when closable is true, a close button is displayed.

Some users complain because it is somehow tedious to click on a small button and would prefer to click anywhere in the toast to close it.

Most of notifications libraries allow it, see eg https://github.com/fkhadra/react-toastify
