Starting the audio file player

Some progress on the audio file player:

• File player panel now allows selection of a wav file when opening files.
• Added a "send to" selector that allows selecting a rack or output as the destination for the audio signal.
• Added gain slider that allows controlling the volume of the audio file.
• Updated session persistence to load and save the selected audio file, target rack and output gain levels.
• Updated Cantable's internal wave file reader to understand Wave64 audio file format.
• Setup the framework for an audio file source object. This is the object that connects the file reader and the audio engine.
• Setup a audio file reader interface that can be implemented for various file types - and provided an implementation for wave files.
• Implemented a new thread pool class that will supply worker threads to handle file reading, sample rate conversion and sample type conversion.
• Implemented code to wire up the audio file source object to the appropriate mixer objects for connecting to specific racks or audio output.
• Started code to allow channel assignments between the audio file channels and the master bus channels.

There's still a fair way to go, but it's a start...
