Allow Javascript errors to be excluded on the front-end

[srtfisher]

As apart of https://github.com/alleyinteractive/logger/wiki/Front-end-Logging you can send logs to the back-end with window.aiLogger.push(). However, this can result in unnecessary requests if the error was filtered out server-side. We need a way to filter out this message in Javascript before the AJAX request was made to the back-end.
