Patron's have the ability to place an unlimited number of suggestions from the OPAC. This has been an issue at some libraries where some patrons will place many dozens or more suggestions at once.

Here's the idea:
1) Add new system preference "MaxOpenSuggestions"
2) Modify opac-suggestions.pl to count the number of suggesions the patron has that are not Accepted or Rejected
3) If that count has reached the number specified in MaxOpenSuggestions, deny the ability to place another suggestion with the message:
"You have reached your limit of suggestions you can place at this time. Once the library has processed those suggestions you will be able to place more"
