Move most label/accesskeys to command nodes

Move most label/accesskeys to command nodes

The following entries had multiple menu items with differing labels.
I picked one for each to be the "default" on the command node.
The others were left on the menuitems.

cmd_edit_copy_buckets (edit/cat)
cmd_edit_volume_buckets (edit/cat, commented out)
cmd_edit_record_buckets (edit/cat)
cmd_circ_checkout (circ/circ/search)
cmd_copy_status (circ/cat/search)
cmd_search_opac (circ/cat/search)
cmd_search_tcn (cat/search)
cmd_search_bib_id (cat/search)

Side note:
cmd_replace_barcode exists on edit, circ, and cat, but used one label for all three.
