Added support for RFC 104, the logging interface: https://docs.google.com/document/d/102b8k5pKYj9e-tMmG53aT5izur-qfUSPX1gBro4gN0Q/edit

Added a dumb implementation of the logger in the D3D11 sample.

Added a method to the WaveWorks API to allow the user to set (override) the internal logger with their own supplied nv::ILogger derived object.
