- Added KDE2 PropsDialog Plugin (incomplete)

- Fixed some KDE related autoconf stuff
- Added PlpDrive class for returning results from rfsv:devinfo
- Added auto-watch in ppsocket and finally got rid of the nasty
    SIGPIPE bug. Now it's no more necessary to ignore SIGPIPE in
    applications.
- Made constructors of rfsv16, rfsv32, rpcs16 and rpcs32 private to
    enforce use of the factories.
- Removed error output in the factories and replaced that by error codes
    which can be retrieved and evaluated by an application.
