New local option --only-names in modules list action.

* modules/modules.eselect (do_list): New local option --only-names
will output names of modules only, without their description.
This replaces the previous brief output mode behaviour and is
mainly intended for bash completion.
(describe_list_options): New function, documents --only-names.
* bin/eselect.in (es_do_help): Don't force default output mode.
* misc/eselect.bashcomp (_eselect): Call "eselect modules list"
with --only-names option.
