xF2 Add-on Alert Improvements by Xon 2.10.13

• Make global "mark read" work without a overlay or redirect to a new page, and reload alerts on the existing page when invoked
• Handle alerts unviewed/unread being out of sync so trigger summarization
• For reaction summary alerts
  • Ensure reactions have stable sorting (new summarizes only)
  • On generating summary alerts, ensure they are treated as just-read correctly in the UI.
  • On viewing details, Fix the new alert star was being put under the avatar incorrectly

• Fix access check when unsummarizing alerts. This could allow deleting arbitrary alerts for other users, but did not leak contents of that alert.
• Fix unsummarizating alerts where not correctly marking the alert as unviewed
• Remove redundant separator when floating mark read/unread right
• Update phrase used by the reaction summary for a single user giving multiple reactions

• Fix "Call to a member function updateUnreadCountForUser() on null" during hourly cleanup
• Remove overlay flag on alert preferences link on alert page

• Tweak read/unread/recently-read row styling, move read/unread separator as css class rather than inline styling
• Restore per-alert 'mark read' link

• When pruning alerts; Reduce maximum batch size, and back-off by 1 second between prune attempts

• Fix unexpected extra queries when a user doesn't have unread alerts

• Even if "Alerts pop-up skips mark read" is set, mark alerts with the content type "user" as read when the alert pop-up is opened. As these alerts never get marked as read by visiting content

• Patch hourly alert cleanup to better respect max job run time

Rename various templates to match XenForo Resource Standards

• The installer does attempt to rename the affected templates to preserve history and custom changes.

• Only delete in batches to prevent issues with galera clustering which can deadlock or stall for large data sets
• Do not constantly change view_date when re-summarizing or un-summarizing alerts to prevent alerts being kept alive forever
