Presentations page for use with mirroring tools

[GoogleCodeExporter]

Implement a web page that displays all the uploaded presentations in an 
FTP-like directory tree.
This way tools such as wget can be used to create an offline archive of 
presentations.
This is useful for presentation computers at the conference.

Such a page should use basic authentication so that simple tools such as wget 
can easily use it without problems.
