mess up some add-on's option UI
and can't display tab more than one line

This review is for a previous version of the add-on (1.0). 

I have made some changes that should fix most of the preference windows with other addons. Please update to 1.0.1https://addons.mozilla.org/firefox/downloads/file/119335/seven-1.0.1-fx-windows.jar?src=version-history

I'll fix the multi row tabs in an update.
