Hi Kris. I think I have fixed this.

There was indeed a bug that prevented plain Nmap XML files from being
compared. The comparison window was checking the Nmap output of each
selected scan against the empty string to see if a scan had been
selected or not. When you loaded a scan whose output *is* the empty
string (a plain Nmap XML output file), it falsely assumed that you
hadn't selected a scan yet.

You still don't get anything from the HTML browser view, because that
only compares the text outputs. Now it gives a more helpful error
message explaining the situation instead of claiming you haven't
selected two scans yet. I decided to allow it to open the browser if
even one of the scans has text output, although it's not very helpful if
only one does because you get an all-insertions or all-deletions diff.
