hydra-ox.el (hydra-ox): Update parameter list

The `defhydradio' spec for each parameter was updated to:

    (name &optional doc value)

This way, it's easy to define this type of hydra:

(defhydradio hydra-tng ()
  (picard "_p_ Captain Jean Luc Picard:")
  (riker "_r_ Commander William Riker:")
  (data "_d_ Lieutenant Commander Data:")
  (worf "_w_ Worf:")
  (la-forge "_f_ Geordi La Forge:")
  (troi "_t_ Deanna Troi:")
  (dr-crusher "_c_ Doctor Beverly Crusher:")
  (phaser "_h_ Set phasers to " [stun kill]))

(defhydra hydra-tng (:color pink)
  (concat (hydra--table hydra-tng/names 7 2 '("  % -30s %% -3`%s" "%s %%`%s"))
          "\n\n")
  ("p" (hydra-tng/picard) nil)
  ("r" (hydra-tng/riker) nil)
  ("d" (hydra-tng/data) nil)
  ("w" (hydra-tng/worf) nil)
  ("f" (hydra-tng/la-forge) nil)
  ("t" (hydra-tng/troi) nil)
  ("c" (hydra-tng/dr-crusher) nil)
  ("h" (hydra-tng/phaser) nil)
  ("b" beam-down "beam down" :exit t)
  ("o" (hydra-reset-radios hydra-tng/names) "reset")
  ("q" nil "cancel"))
