I changed some elements in the interface.
No break in binary compatibily (no crash), but some details.


0.7.0.x --> 0.7.2.1
-------------------
- MediaInfo_Stream_Video --> MediaInfo_Stream_Visual
  (conformance with MPEG consortium names, Visual = Video or Image)
  Note: this is only if you use named options, the number is always "1",
  old programs will not have problems with this.
- To detect if this is a video or an image, you can test "Animated".
  Is 1 if this is a video, 0 if this is an Image
- MediaInfo_FileOption_Close --> MediaInfo_FileOption_CloseAll
  Note: better name only, the number is always 2
  old programs will not have problems with this.
- Values of MediaInfo_FileOption_* are precised
  (because these are binary flags)
  Note: precision only, numbers are always same
  old programs will not have problems with this.

0.6.x.x --> 0.7.0.x
-------------------
- Inform() : Option_Custom is deprecated
  - if "Inform" option is set, it is used. Unset it to have a "normal" view.
  - To have a HTML output, use Option("Inform", "HTML") before.
  I will change the documentation as soon as possible
- Tags : Somes tags have changed :
  - "Channels" is now "Channel(s)"
  - "Track" is now "Track/Position". Be warned : "Track" is used, but for other things
  - "Title" is now a generic name for 2 different names :
    - "Movie" for a movie (video and audio) name
    - "Track" for a track (audio only) name
    "Title" will always exist, you can continue to use it for a generic access
  - "XXX_String" are now "XXX/String"
