* modules/gui/skins/src/vlcproc.cpp: small compilation fix.

* src/libvlc.c: forgot to reload the command line options after we reload the main module when the user disables the translation.

* Makefile.am: added a dist-hook target to include the auto-generated msvc files into the dist. added src/misc/modules_plugins.h to the dist.

* modules/gui/skins/src/themeloader.*: dropped the dependancy on libtar
   for the .vlt skins support. libtar is still used if present, otherwise
   we use our small implementation of untar.

  strings and "...". i18n seems OK under BeOS now.

* modules/codec/libmpeg2.c: make sure there are no more linked pictures
   left when closing the decoder.

* modules/audio_filter/converter/s16tofloat32swab.c:
   added an #ifdef HAVE_ALLOCA.

* configure.ac.in: don't link with the math library on win32. It isn't
   needed and will even screw up things under cygwin with -mno-cygwin.

* gtk2_api.cpp: made valgrind happy ;)

 * modules/gui/beos/*: added _()s so the whole interface is translated
 * src/libvlc.c: ask gettext for UTF-8 strings (under BeOS only for now)
   FIXME: currently, untranslated strings are not converted to UTF-8

* modules/codec/libmpeg2.c: fixed aspect ratio problem.

 (Window is already a Xlib type !)
  *** not tested under win32, please check ! ***

*All: fixed unwanted fileinfo window refresh under windows.

* modules/misc/network/ipv4.c: a bit of cleanup.

* a bit of code cleaning

* configure.ac.in: print an error message if libmpeg2 is not found or too old.

* configure.ac.in: the libmpeg2 plugin is now enabled by default when the right version of libmpeg2 is detected (0.3.2 aka cvs).
