Went through a significant portion of the back log of bugs in the MediaWiki/File management component.
- Made a note of bugs that I think need looking into. Recategorized one's that were improperly categorized. Closed some bugs that were already fixed (14 less bugs in the component. Out of 282 bugs at the start)
Fixed a bug in unit tests that decided to drop my user table (bugzilla:65654).

Became acquainted with the situation surrounding the Fae thumbnail outage.
Submitted a patch to make image renders for tiff files > 50 megapixels be no-ops instead of the current situation where they download the hundreds of MB big file only to throw away the download. I suspect this is a major part of the load issues on the image scalars since failed thumbnailing attempts have only a very short lived cache.

Worked on adapting VipsScaler to work on tiff thumbnails so that we can scale larger files
Locally this was successful, with the three biggest tiff files I could find on commons being scaled inside resource limits similar to Wikimedia's.
