with --enable-shared-libvlc

- pre-create 'width' and 'height' in libvlc so that the ActiveX plugin can set them before a vout is created. this prevents the initial viewport resizing when playing the first target

all: reworked ActiveX plugin, which now works properly  with .NET (tested with Visual Basic Express 2005)
     added persistent properties such as MRL, AutoPlay, AutoLoop which allows a user to play a default target
     without programming.

* use autoconf 2.59 instead of 2.57, since bootstrap needs it now -- this breaks the compilation on BeOS, but there is no way to prevent that except making bootstrap autoconf 2.57 - compatible again

(patch contributed by Marco Munderloh)

you watch the playlist when it is called but i can't find what's wrong.

  I said "experimental". I meant it.
  Developers might try --enable-shared-libvlc
- remove autom4te*.cache on bootstrap
  (some customized autoconf add their version number)
- some clean up

and all its children.

Fix 64 bits build (Debian #324031)

 * skin_parser.cpp : add comment so people know where to look to fix the
                     Playlist slider breakage.

Slower maybe, but safer
and arguably more suited for automatically issued tarballs

(wanted to cancel, but I pressed the wrong key)

bootstrap might be a little slower,
but that'll ensure more recent build-system in tarballs.
Besides, 

   work, cleaning and fixing. I'll continue this weekend.
