New Methods to Support Multithreading

 To support the writing of multithreaded applications, the following methods have been added to the following classes:
WOApplication
Method Description
adaptorsDispatchRequestsConcurrently Returns YES or true if at least one adaptor contains multiple threads and will attempt to concurrently invoke the request handlers.
allowsConcurrentRequestHandling Specifies whether the application has been written to be able to safely handle concurrent requests. By default, returns NO or false. Subclasses should override to return YES or true if the application is written to be thread-safe.
isConcurrentRequestHandlingEnabled Returns YES or true if the application can handle concurrent requests and the adaptor will dispatch requests to the application concurrently.
lockRequestHandling Serializes request handler access through the use of an internal lock if concurrent request handling is disabled. Request handlers should invoke this method before calling into application code.
unlockRequestHandling Removes the request handling internal lock to allow access to the request handler again.
