Patch for RealPlayer in ubuntu-docs/natty

[peppe84 at linux.it]

Hi all

We have a little problem with RealPlayer instruction, cause are obsolete.

Also:
- RealPlayer is not in official repository
- RealPlayer is not in non-official repository such as medibuntu
- There are dependencies problem with official .deb packages [*]
- Install .bin file is the way.

But, in the future, dependecies problem can be resolved and we need to
edit official documentation again.

My solution is delegate this argument to community documentation. I have
create a draft [0] for this. Feel free to edit and replace it in the main
page.

With the attached I have edit this file:
- internet/C/web-apps.xml : delete "real" word at line 55

- musicvideophotos/C/music.xml: at line 286 replace link from
video-realplayer to video-playback-streaming

- musicvideophotos/C/video.xml:remove totally video-realplayer section
from line 168 to 214. Add link to community documentation in
video-playback-streaming.


Ciao!
