Pukka 1.7.1: user experience bug fixes

I've just released Pukka 1.7.1, available here, to address some user experience issues. This release features better keyboard navigation in the main and preference windows, some minor bug fixes with the preferences involving showing the accounts in the dock and menu bar, and it ensures that the most recent bookmarks are shown by default, something that wasn't quite working right in 1.7. Enjoy!
