Start the dream manager even if dreams are not supported.

Browse Source 
The dreams manager also manages dozing.  It has a minimal footprint
so there is no real reason to disable the component (it just makes
debugging more difficult).

Improved the documentation of the config_dreamsSupported resource
to clarify exactly what it controls.

When true, the system will allow the user to configure dreams (screensavers)
to launch when a user activity timeout occurs or the system is told to nap.
When false, the dreams feature will be disabled (this does not affect dozing).
Consider setting this resource to false or disabling dreams by default when a
doze component is specified below since dreaming will supercede dozing and
will prevent the system from entering a low power state until the dream ends. -->
