Fixes #138

Allows the client to be changed on a ticket. Previously, only the
information about the client associated with the ticket was editable. This
patch permits assigning a completely different user to the ticket.

Fixes a case where multiple tickets are created in one request (such as a
cron job triggering multiple email fetches). The TicketForm::getInstance()
called in Ticket::create() used a singleton pattern to retrieve a cached
instance of the TicketForm. In the case of ticket creation, each ticket
needs a new TicketForm entry instance.
