Bug 1195767 - part 5 - use signaling instead of broadcast when work items are placed in nsEventQueue; r=gerald

Browse Source 
There's no reason to wake up all the threads in a thread pool when one
item gets placed in the queue.  Waking up one will serve the same
purpose and is significantly more efficient for thread pools with large
numbers of threads.
