Changes to button structure with an added icon throw off the CSS selector for primary and destructive buttons.
PFly has no notion of images in buttons, so removing the images fixes the color
Added missing files.  I suspect most of these aren't ever used, just automatically loaded, but can't see where.

Bz1119372 button text color
Changing light-yellow for light-blue. It was used on the date picker and the EnhancedSearchBar component (the color for hover effect)
Calling Pace.restart() instead of Pace.start() because it was not working if two calls of Pace.start() happened after each other. restart() is a suggested way of calling the progressbar manually.
[1115725] Operation history continues to grow unbound with no easy way to purge old history
Add operation history purge to the data purge job.  A new system setting
is added with a default of 0 days, which means disabled. The db-upgrade
will add the new setting, also set to 0=disabled so that upgrades don't
automatically force an unexpected purge of operation history.
Also:
- cleaned up some I18N when adding the new properties, removing some
  duplicates, adding commented, missing translations, etc. Some touched
  files were only due to some remvals of deuplicate I18N properties.
- added DatabaseType.getLimitClause() although in the end I didn't use it.
Gray background for each EvenRow even if it is currently disabled.
