Subject: 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.
