load module "ice-9 format"
add load access button

open/closed/gone
Adjust CSS spacings to accommodate
break out components of load slot

Each component (name, scratch, role, alt) gets its own factory
function rather than being covered by one giant format string.
implement self-manifest control

A load's state can be "open", "closed" or "gone", visually indicated
by color. In any state other than "open", self-manifest is disabled
at the kiosk (load slot forms are disabled). Admin workstations
always have full edit privileges regardless of load state.
