XWIKI-9373: Extend HqlQueryExecutor to use setParameterList for list type parameters passed with bindValue
XWIKI-10286: XWiki#exists returns false for document translations
XWIKI-10289: "java.lang.IllegalArgumentException: Comparison method violates its general contract!" on Java 7
XWIKI-9551: When you delete a user from the main wiki it is not deleted from the subwiki groups
[misc] Remove unused dependency
XWIKI-10290: Empty HQL query throws exception
XWIKI-10292: Move XWiki.GadgetClass from XE to the platform-dashboard-ui module
XWIKI-10293: Missing translation keys for the reference type in the include macro
[Misc] Add missing dependency (dashboard-ui needs the dashboard macro to work)

Note that IMO the dashboard-macro module needs to be modified to generate the GadgetClass instead of providing it as a XML page in dashboard-ui since the dashboard macro will not work without it...
XWIKI-10274: Also send system information when saving Active Install pings
XWIKI-10273: Add history support to Active Installs
