add support of burp project files

[blshkv]

burp project file is a single "live" file which records all logs automatically and this is the preferable way.
The current approach (to export logs manually) seems not very practical.

btw, sqlmap can parse burp/webscarab log files, see:
sqlmap -l LOGFILE

So ideally, you should push your work back to sqlmap instead of creating yet another one-day script.

While I'm not 100% sure on the difference in XML structure between log files and project files, my hunch would be that this should be an easy improvement.

You should push your work back to sqlmap

Once the project reaches a more stable state I'd definitely be open to this. Thanks!
