Added default constructor for Semaphore 

Currently Semaphore can not be instantiated without an explicit count
as a constructor argument. This limits where Semaphores can be declared
and requires explicit initialization in several annoying places, such
as in member variables and SingletonPtr targets.

This adds a default count of 0, which has shown to be the most common
initial value used for semaphores.
