Warning Improvements by Xon 2.12.5

This add-on is no longer in beta and can be considered feature complete and stable.

Changes from beta:

• Only send warning email if the user has an email address
• Fix category sorting
• Add {userId} as replacable for warning conversation
• On issuing a warning, redirect back to the content via the getContentUrl() instead of referrer
• Display user's warning count on the "previous warning" bar, make the previous warning count configurable (default 5) and link to the rest of the warnings if not all are displayed.

• Improve installer
  • Ensure phrases are not reset on upgrades
  • Setup defaults for the Custom Warning on install
  • Tweaks to prevent unexpected __conflict column renames on upgrade

Note; this is likely the last release candidate baring unexpected bugs.

• Fix "Cannot use \XF\Entity\User As User because the name is already in use"

• Fix being unable to save display order for warning definitions
• Fixes to posting various warning/warning summaries to threads (new & existing)
  • Respect the user settings or default user to post as
  • Ensure notifications are sent
  • Default forum prefixes are respected
