* Finally fixed that weird To/Cc/Bcc bug (it might be with PHP or browsers
  or whatnot -- but this now works properly).

Bug description:
  - Add multiple people to your address book
  - Select lots for the To, and one for CC or BCC
  - When you return to the compose form, the To list would be right, but
    the CC and/or BCC list would have extra addresses appendeded.
  - Extremely weird.  Seemed to have a cascading affect, as though the CC
    array needed to be >= the to array, and likewise for the BCC >= CC size.
