Lunch-break bugfixes for Notational Velocity ALT

I’m going to have to build a project page for this, and probably set up a separate Sparkle feed for updates on this fork. I had a few minutes while eating my peanut butter and jelly, so I’m posting a new build with a few changes:

• Links in rendered previews open in external browser
• Source view works better for Textile documents
