Better UI for Options screen

It's a messy, confusing screen.

1. By default, the services should be hidden on the options page, with a button to toggle "Show Advanced Options". That will reduce the confusion for new users, so they can easily see simple options to choose the default service and mode.

2. There is a lot of wasted space around the form elements in the advanced options (Bible Services). Convert the layout into a table, and use a content-editable functionality that will convert the table cells into input fields when clicked.
