* 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 ;)
