MJPEG Tools Svn

* Remove "#include config.h" from all *.h, *.hh, *.hpp files
* Add "#include config.h" to all *.c, *.cc, *.cpp files
* fix one of the best stupidities I've ever seen in lavplay.c (see diff)
* Make everything be built using libtool (except libmjpegutils.a, *)
* Fix compile error in PS_Stream because the virtual class has a non-
virtual destructor
* Install all mplex headers for libmplex2.so
* Get RPM building back working
* Fix make distcheck

I'm now able to compile externel projects against libmplex2.so, great job
Andrew!

(*) How do I do static-only but installable libtool builds?
