Note that this fixes contradictory default values for group
"Preferences", key "Home". This is exactly the kind of errors I want to
prevent with this new style.
The hope is that this can later be used to:
- verify that all accesses to the same key use the same default value,
- and extract the default values more easily.
Corrects a slew of titles, buttons, labels, menu items and status bars
for capitalization, ellipses and punctuation.
Rewords a few actions and dialogs to use uniform language and
punctuation.
This adds a checkbox to enable autoplay on all websites (disabled by
default) and a website list to enable autoplay on individual websites
(set to file:// URLs only by default).
