Redirect when a folder contains only a single file

[DannyBen]

This PR adds and fixes several issues:

• Redirect directly to the file, when it is the only one in the folder and there is no README in the folder
• Add debug log facility - just use log something anywhere. Output is in madness.log
• Added favicon stand-in, just to prevent the requests from being empty and interfering with debugging
• Add HTML title - will now show the name of the document instead of "Sinatra Baseline".
• Remove debug local from the server and view
• Add #title to the Document object. Used in the Auto H1 and HTML title
• Closes Auto show only file in a folder #7
