All code in the lib folder is now merged into a single Cortex.dll

This should cut down greatly on compile time and simplify linking.
Deleted the library specific makefiles.
Fixed the Makefile in main to reference the new cortex library
Changed the black list to only include Cortex.dll
Fixed appdomain creation to call Cortex.dll instead of Libraries.Filters.dll
Updated makefiles for all the default filter packages to reference Cortex.dll
Fixed all of the make files for format conversion
