/* Result of some quick night-coding, so don't expect much.
There should be a show.db sqlite3 database with a schema like 
in line 22. 
If there isn't a new one is created with helloworld as a default password.
New passwords can be created, they are stored as sha1() hashes.

One can create a new link on show.php?mode=admin; the file names are paths on the web server.
The links are going to look like this: show.php?session=SESSION
