Improve Logging for Fuppes

[Robert Massaioli]

I want to improve logging for fuppes, ideally we would log everything to a file and we would poll from that file when we want more information.

The features we should have are:

• Concise one-line logging so that logs are easy to grep.
• Log levels should be printed to the screen so that we can visually see which items are causing problems.
• Log lines should be as concise as possible.
• The concept of log 'groups' so groups of items that come under the same section.
• Dynamic logging that can be turned on and off (or have its log level changed) while fuppes is running. This would allow us to live debug a running problem.
