Major API cleanup. Unified formatting & doxygen tags in the public API.

Added factory provider for default log streams.
Added default log streams to std::out and std::cerr.
Updated VC8 project config, boost workarounds is now working for the viewer.
Updated unit test suite.
Fixed some minor issues in the postprocessing-framework.

BROKEN: DebugDLL build.
