A bunch of various log spamming coming from WKWebView... and the solution for most of them is to turn off logging (like here: https://stackoverflow.com/a/64588439/13569127). Unfortunately, that turns off our intended logs as well!

A few silenced logs:

• Major spam was coming from event logging - was logging 2x/min or so, no matter if we had anything to post or not. Now we're only logging if there is something to post.
• "113 error: Could not find specified service" - Once we added the article's webview as a subview of ArticleVC, most of these disappeared (https://stackoverflow.com/questions/44585980/com-apple-webkit-webcontent-drops-113-error-could-not-find-specified-service)

• Not worry about: A bunch of WebView logging. Some because it's hanging around for a half second as we deallocate it. Apple says don't sweat it: https://developer.apple.com/forums/thread/11209

• convert os_log statements to DDLog
• convert NSLog statements to DDLog
• convert print statements to DDLog
• Improve DDLog output to be more actionable (no double timestamps, etc.)
• Prepend [info]/etc. to lines. (Maybe w/ emojis - stop sign for error, etc.)
• DDLog is actually funneling through NSLog - hence the two timestamps and such
• Add in colors? https://github.com/CocoaLumberjack/CocoaLumberjack/blob/master/Documentation/XcodeColors.md
• convert to os_log, drop CocoaLumberjack?

I did not worry about any logging within testing classes, as well as the print statements within the localization/language command line tools and scripts.
