Reorganised the source tree. We now have src/ with a couple of subdirs:
* daemon/ - Contains the files specific to the polypaudio daemon.
* modules/ - All loadable modules.
* polyp/ - Files that are part of the public, application interface or
are only used in libpolyp.
* polypcore/ - All other shared files.
* tests/ - Test programs.
* utils/ - Utility programs.
