Added configurations to `bumblebee` package to easy multiple monitors on Optimus machines. The behaviour of the default `bumblebee` package hasn't change, so this change is backwards compatible. Users who want to connect a monitor to their discrete card should use the package `bumblebee_display` instead. Also added new configuration option to nixos bumblebee module: ``` hardware.bumblebee.connectDisplay = true ``` will enable the new configuration, but the default is still false.
