  Fix broken mailbox parsing when searchcontexts option is enabled.
  
  When using the searchcontexts option in voicemail.conf, the code
  made the assumption that all mailbox names defined were unique across
  all contexts. However, the code did nothing to actually enforce this
  assumption, nor did it do anything to alert a user that he may have
  created an ambiguity in his voicemail.conf file by defining the same
  mailbox name in multiple contexts.
  
  With this change, we now will issue a nice long warning if searchcontexts
  is on and we encounter the same mailbox name in multiple contexts and ignore
  any duplicates after the first box. Whether searchcontexts is enabled or not,
  if we come across a duplicate mailbox in the same context, then we will issue
  a warning and ignore the duplicated mailbox. I have also added a small note
  to voicemail.conf.sample in the explanation for searchcontexts explaining
  that you cannot define the same mailbox in multiple contexts if you have
  enabled the option.
