Platform Engineering Team/Personal Development Share Back/Maintenance/Features for DisplayTitle, TitleIcon, CommentStreams, and PluggableAuth extensions

Idea
Prior to joining WMF, I developed a suite of extensions that I still maintain on the side as a volunteer. I have developed a backlog of tasks for those extensions, since I have not had the time to devote to them recently. I have selected some tasks that I plan to work on in 10% time and added them to my volunteer workboard at.

Outcomes/Goals

 * Reduce the backlog of tasks related to the selected extensions
 * Fix bugs and bring new requested features to enterprise MediaWiki users
 * Keep my programming skills sharp

Reviewers
There are several tasks that would benefit from discussion with team members, if their time permits. In particular, one or two of the tasks may be good candidates for Knowledge Sharing with Brad.
