Uses `mw.trackSubscribe` to create an intermediary data handler
named `wikimedia.PageIssuesAB` which extends event-logging data
before passing it to the eventLogging through `wikimedia.event.PageIssues`.
Event hooks are placed where appropriate and the `CleanupOverlay`
class is extended to capture events from within the page issues
modal.
Additional changes:
* Merge two identical on click event handlers for
.edit-page, .edit-link elements
* change pageIssueParser.maxSeverity to accept an array of severity levels
instead of an array of pageIssues objects

- Fix a bug where the all issues endpoint would incorrectly collect
issues from all sections.
- Update the page issue iconography. This increases the size of the
delivered code and images by 1743 B minified uncompressed according to
mw.inspect() (from 16.4 KiB to 18.1 KiB).
- Add support for identifying page issue severity based on template CSS
classes.
- For multiple issues templates, show the highest priority icon.
