Bug fix kimchi-project#189: Forcing download of user log file

The error in staticfile() happens when the browser tries to open
a recently created file in a separated tab/window but this file
isn't declared in the cherry-py config with tools.staticfile.on,
like '/favicon.ico' for example.

A suitable solution to avoid the error is to force the browser to
download the file instead of opening it. According to the Cherry-py
docs:

"Using "application/x-download" response content-type, you can
tell a browser that a resource should be downloaded onto the
user’s machine rather than displayed."

This patch set the application type of all '.txt' files created
under the /data/logs dir as 'application/x-download'.
