Xenforo Alert Improvements by Xon 2.9.5

Fix "Alerts pop-up skips mark read" and "Alerts page skips summarizing" user-options did not save as expected
Fix "Alert resummarize flood check" global option didn't allow selecting 0 to disable it

• Require php 7.2+
• Require XenForo 2.2+, remove XF2.1 support
• Fix sticky unread alerts could unexpectedly occur due to (effectively undocumented) 'auto read' functionality in XF2.2
• Fix confusion over view_date vs read_date not being correctly used in the expected places
• Fix alerts pop-up not respecting "Days to retain viewed alerts in popup" option in all cases
• Fix 'mark read' functionality could result in inconsistent view/read date for older alerts near the expiry period
• Fix unstaller not correctly removing columns added to xf_user_option
• Fix alert summarization/grouping may not trigger when expected
• Ensure xf_user_alert.summerize_id column has the same column size as xf_user_alert.alert_id. If alert_id has been to a bigint, this may be an expensive operation;
  
  SQL:

  alter table xf_user_alert modify column summerize_id bigint unsigned  default null;

• Use index hints to control poor index selection on some installs
• Attempt to improve unviewed alert cleanup which can have issues when dealing with very large number of alerts
• Improve UI.X compatibility
• In Alerts pop-up, do not prevent marking alerts as recently read when they are read in that request
• Add various styling options to control alerts styling
• Add styling option to control if just-read-alerts from the alerts pop-up are styled as read or unread, and if to fade from unread to read.
• Visiting the full alerts page no longer marks alerts as read by default, and removes the relevant per-user option ("Alerts page skips mark read").
• Display an font-awesome icon (star with exclamation) on alerts which are unread with auto-read off, rather than a star for recent-ish alerts. With more correct hint text on both
