Subject: [PATCH] Implimented Ignore CEC for Chromecasts

1) Added the ability to ignore CEC data from Chromecasts using pending
updates to PyChromecast library.
2) Modified cast device to not allow the same device to be imported
twice. This can happen when cast is setup as a media_player in the
config when the discovery component is active.
