This experiments with making PageIssuesOverlay an Overlay with
various options.
The appending of children is a little messy and points at a need
to standardise this some way
(see https://phabricator.wikimedia.org/T209647)
TODO:
* Remove the iconString property on PageIssueSummary which is no longer
needed
Bug: T209647
Change-Id: Iadd798a820dca6bbb31edc9a8570b6db7aac237a
The CleanupOverlay is moved to Minerva and renamed the
IssuesOverlay to be consistent with current terminology
The new IssuesOverlay is defined inside the module
skins.minerva.scripts to which it now belongs.
Additional changes:
* various file renames
* overlay-cleanup renames overlay-issues
* cleanuptemplates renamed issues.js
* Add a test stub file to avoid the need to load templates inside
the test environment
After this change, I75f47622d94e504688e04dfb2892540473817053
should be merged to avoid confusion.
