Move page issue overlay specific code out of cleanuptemplates and into
PageIssueOverlay to clarify what code is specific to the page issues
modal screen and what's specific to the page itself.
Bug: T191528
Change-Id: I95821ccda84306ddd5d22b57ffbae8d13ca44408
Rather than inventing its own page token the PageIssues
schema will rely on the standard page token.
In future when I9bb18d47e36d2d99d812e5b47ea9516d3dff3a16 is
merged this will mean that PageIssues and ReadingDepth have
consistent page tokens.

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.
