This doesn't change the alerting UI logic, it just turns
alert_words_ui into a module and calls the setup code from settings.js
when the settings page is rendered.

This fixes a mild regression in 6bd2a0315ff56a20027074d65ccaa094bd35e63f,
which fixed a bigger bug. That change added the event parameter to
add_alert_word(); this change updates one of the callers to now
supply it.

The global in question was `event`, set to:
MouseEvent {dataTransfer: null,
toElement: button.btn btn-mini add-alert-word,
fromElement: null, y: 442, x: 763…}
in Chrome. This does seem to be the correct event.
In Chrome, this global variable existed, so the code path didn't error
out. In Firefox, the global variable didn't exist, causing adding
alert words to fail.
