Title: Adding max_search_queue config file option to limit number of threads waiting to search

As discussed in issue #36. This adds an option to the indexengine config file called "max_search_queue", which sets a limit of the number of threads waiting to acquire the search semaphore in TrafficLimitingSearcher. The default value is currently 100 (before there was no waiter limit).
