[dev] Locked-Info on AgentTicketStatusView

[Alexander Scholler]

Hi,

AgentTicketStatusView shows all open tickets, regardless they are locked 
or unlocked.

But to get a real fealing about the status of working on tickets,
I added the column "locked" to status view by modifying the source code.

It would be great if this could be configured in further otrs versions 
within Sysconfig:
* mini feature: shall "locked"-info be added to status-view?
* great feature: individual configuration of columns/ticket-properties 
displayed

Bye, Alex
