Flags will be reimplemented as a separate feature.

Crowdin seems to have difficulty parsing YAML files with spaces between list
items. This patch avoids the issue by removing unnecessary empty lines in
the file.

Changed Resolved to resolved state
Add ability to get statuses by states

Ticket numbers are now configurable as a system-default and by help topic.
Previously, an administrator could select between six-digit random and
sequential numbers. Now, the sequence is selectable so multiple sequences
as needed, and a format can be specified to define how the ticket numbers
look. Formats can also be defined for each help topic.

DynamicList initial data

Add TicketStatus class and ticket_status table

Starting with osTicket 1.8.1, users must receive an email and follow a link
in the email to get access to the ticket. With this new option, the email
verification step can be avoided in osTicket 1.9, because access is now only
granted to exactly one ticket.

The user should not have to step over it
