* Tweak staff photos for a couple of users
Added tooltip over user image.
Added current .crx to repo to help non-Catalyst users.
Added category overrides.

You can now put config in the WR details field to map statuses to specific ticket groups.
For example, for NZRS, do
    [kanban:Pending QA->Test]
    [kanban:QA Approved->UAT]
You can only have one mapping per line, but as many mappings as you like.
Added staging/UAT servers to match list.
Tidying up logging.
Added ghost WRs to work around WRMS bug #214735.
Packaged v0.6.11.

Note that this version will be automatically disabled by Chrome after
the upgrade - you need to manually approve the extra privileges it
requires to access two WRMS testing servers.
Removed additional servers (nicer upgrade path), built in the NZRS overrides as standard for that Organisation.
