Subject: [PATCH 1/3] Add tab for viewing the debug log

This adds a tab where the user can easily see the last X lines of the debug.log file.

Currently it shows the last 100 lines as of the time that SD starts up. Next will be
to have a way to show updated data (such as a refresh button) and allow customizing
the number of lines to show.
