Action Command Notification support

New in version 1.4.1.

The OctoPrint Action Command Notification Support Plugin comes bundled with OctoPrint.

It allows firmware to trigger notifications users with the PLUGIN_ACTION_COMMAND_NOTIFICATION_SHOW permission using action commands about relevant events.

The notifications in the sidebar panel can also be cleared by users with the PLUGIN_ACTION_COMMAND_NOTIFICATION_CLEAR permission.
