Pid removal

    
    SickBeard is happy to create its own PID file, but doesn't remove it when
    killed by start-stop-daemon(8). Upon being restarted, it find the previous P
    file, assumes it hasn't been stopped properly, and refuses to restart.
    
    This ini.d script change fixes that, by letting the stratup script remove th
    PID file after start-stop-daemon(8) has terminated properly.
    
    At the moment, this fix probably does not handle incorrect terminations such
    power cuts well, as the PID file would still be there at the next boot, but 
    SickBeard process obviously not.  This problem would probably be better fixe
    by letting SickBeard check whether the PID recorded in the PID file is still
    running SickBeard instance.
