Fixed bug#[10041](http://bugs.otrs.org/show_bug.cgi?id=10041) - Queue Based Calendars not shown only the standard calendar is used.
Datepicker is now using SLA/queue calendar if shown in connection with existing tickets.
Fixed bug#[5252](http://bugs.otrs.org/show_bug.cgi?id=5252) - For pending- and escalation-notification only the standard calendar is used.
Sending of pending reminders, unlocking of overtime tickets and sending of generic agent escalation notifications will now respect SLA/queue calendar.
