- Make the settings a scroll area. This makes it work on smaller screens and
if more items are added in the future, the dialog doesn't get bigger.
- Made the additional settings label bold to distinguish better.
Also removed the colon, as I felt it wasn't needed because it is
now bold.
- Made the margins consistent between the settings and events pages
- Made the scrollbar show only when needed in the events page
- Moved the remember settings checkbox to the top of the settings because
it just seems better to be there.
