Rename and reorder some prompts and modify some help texts.
The result:

  -------------------- IEEE 1394 (FireWire) support --------------------
  *** Enable only one of the two stacks, unless you know what you are doing ***
  New FireWire stack, EXPERIMENTAL
    OHCI-1394 controllers
    Storage devices (SBP-2 protocol)
  Stable FireWire stack
    OHCI-1394 controllers
