some more status condition follow-up

- Don't display 'Held' when swallowed.
- Don't display 'Held' when the hero is doing the holding; add a condition display
  entry "UHold" for that (the opt_in option is "holding")
- Allow resorting of the 'O' menu for status condition fields. Default is alphabetical, but you
  can sort by condition field ranking now.
