Updates:

# Added new filters in aiosc_TicketManager::ticket_update() for pre-filtering subject / content & other params.

Fixes:

- Fixed Last Update sorting in ticket list
- Fixed general sorting issues in ticket list (front-end)
- Cron table creation query is fixed.
- "Re-Open ticket" button in front-end template was visible only to staff members. It is now visible to customer as well.
- Fixed "Post reply" button. It was missing if "Allow Attachments" option was disabled.
- Single-reply template (shortcodes/single/reply/single.php) was loading only from plugin directory, even if you had it in theme's directory.
