Title: Ignore ActionView::MissingTemplate

# Why?

* `high_voltage` tried to handle unknown URL paths, such as spiders looking for a `rss.xml` file.
* Exception notifier warns us about `ActionView::MissingTemplate'`.

# What Changed?

* Added `ActionView::MissingTemplate'` to list ignored exceptions.
