Remove the FusionTablesControl from visibility

Moved the FusionTablesControl from the STORAGE to the INTERNAL
category. This means that projects that include the control can load,
but people working on new projects cannot add the control to their
project.

Also updated the documentation to include the warning that it is
shutdown.
