* http: rework of the http interface. 

 There is no more hardcoded html page. The interface recursively parse a
directory, exporting all  files. All .htm/.html are  parsed, and special
macro are  used. I will commit  somes samples pages in  share/http and I
hope documentations.

 TODO: - (re)implement access control in httpd (but in a useable way).
       - clean login/password management. (for now .access protects
       a whole directory).
       - doc ;)
