Lots of UI changes so I decided to bump up the minor version to 6.
New navigation for frames makes it easier to see if a webpage has inline frames without having to click on the select box. Since the "Page:" label is gone, one must now navigate to the rules window and double click the header displaying the number of domains and rules to get back previous functionality. A title attribute has been added to the page select box.
Few UI tweaks to fix some offsetting issues with the main window.
Setup window has been removed from the popover in favor of the new settings UI. Upon installation, the settings page will automatically open.
