* don't try to reconnect if its the current device

* add cast button to top bar

* format sessions api

* more formatting issues fixed

* add snack bar to tell user that we cannot cast an asset that is not uploaded to server

* make casting icon change to primary color when casting is active

* only show casting snackbar if we are casting

* dont show cast button if asset is remote and we are not casting

* stop playing media if we seek to an asset that is not remote

* remove https check since it works with local http IP addresses

* remove unneeded imports
