Scanning page: add more info

This is a little idea for improving the user-experience

In the scanning page, the one that refreshes automatically every 5 secs, it would be nice to see the latest changes (addition/updates/removal). maybe you could display there an extract of the log file?

I see 2 benefits:

1. the user sees what is beeing processed, it's always interesting
2. In case of a problem, it would be seen there (if you dump the log in there); I've missed a java heap memory several time until I had the idea to look in the log file to see the error message
