The Samba4 How To in the wiki, and Samba naming

[Marc Muehlfeld]

Hi,

I used this sunday afternoon to completely re-write the
   https://wiki.samba.org/index.php/Samba4
page.

I tried to create a central place where everybody (users/admins/developers) 
could start when using the latest samba version (4.x) to find documentation to 
everything around samba AD/member servers, etc.

The most of the AD section articles are currently linking to subsections of 
the AD howto. I don't wanted to cut it down in separate howtos yet, before I 
got feedback from you.

I tried to keep this new page simple and I don't wanted to place to much text 
on it. Users/admins/developers should easily find articles/howtos they are 
looking for. And I think to much other text on this page makes it confusing. 
Other text should be on linked pages then.

I tried to collect the most s4/AD related pages, I could find on the wiki and 
group them. Currently I haven't thought about the order of the links in each 
section. So maybe some more important articles should be moved up.

What do you think about my draft of this central page?

If you think this draft is a good start, I can finalize it and try to rework 
other pages too and split down the AD howto into a basic installation and move 
everything else to new separate pages.


Regards,
Marc
