Alert Improvements by Xon 2.12.2

• 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

• Compatibility fix for 3rd party add-ons which replace an expected ArrayCollection object with an array

• When summarizing alerts hopefully reduce the chance of deadlocking, and if it happens gracefully recover

• Fix XF2.0 support, and prevent duplicate queries on XF2.1
  

• Fix AdminCP User edit setting 'alerts page skips mark read' to the same value as 'alerts pop-up page skips mark read'

• Fix that marking extra alerts as read was not working as expected with XF2.1+

• Fix "Group alerts" option to group by day, and not per-minute
• Use phrase groups for 'yesterday/today' phrases to avoid extra SQL queries
