Code metric information

Via the Irrlicht blog, I've discovered Ohloh. This looks like an interesting site for deriving various code metrics. You can register your public SVN in the site and it'll pull lots of information off. I'll pull some stats off of it for Unangband, once the registration process for the project has downloaded and analysed the project SVN. Of course, as always you can take the code metrics with a big pinch of salt.

A note for various Angband variant developers: I've added the Angband license by directly copying the contents of copying.txt from the Angband copying.txt. I hope this was the right thing to do.

Unfortunately, it's listed under 'The Angband License' as opposed to 'Angband license'. Doh!
