hc: turn the startup prompt off, as saved by the settings panel

show_prompt set to false. The rest of the diff is the panel's canonical
rewrite of the file on save: it writes prefsCopy(), which is the schema
defaults merged with the file, so key order follows hcschema and delta_z
and delta_ow round-trip as the floats the schema declares them to be
rather than the ints that were in the file.
