Bundle Preferences

Using the regular font size in the bundle and variable tables in the preference panes makes the tables seem a little too busy for me. Also, the default (minimum) size of the panes does not allow much of the description for the bundles to be seen. So in cases where the text could be really long and horizontal scrolling in the table view is not allowed, I prefer to show as much as possible. Apple has a few examples of using smaller font sizes in tables for these situations such as the "Password" pane in Safari and "Key Bindings" in Xcode. Since this is really a personal preference, feel free to just disregard this pull request.

As for the search field in the preference pane, I decided to keep it simple and just filter based on the bundle name and not to try and highlight the matches, since it would require refactoring the datasource.

btw, I plan on doing clean builds form now on before sending pull requests.
