Subject: [PATCH] [IfcConvert] Added IfcRelConnectsElements to xml export
 (#2197)

* [IfcConvert] Export tasks in the xml conversion

The exportion in the XML format exports in a new tag, named "tasks", all the tasks from the file with a hierarchy. Each task contains the IfcTaskTime object if it has it.

* [ifcConvert] Add related objects in tasks

* [IfcConvert] Added IsSuccessorFrom and IsPredecessorTo in xml task export

* Get IfcTasks from IfcWorkSchedule

* [IfcConver] Changed OperatesOn hierarchy level in xml task export

* Added task to property / quanty relationship

* [IfcConvert] Added calendars to xml output file

* [IfcConvert] Added Output objects in the XML file

* [IfcConvert] Fix crash when IfcWorkCalendar does not contain IfcWorkTime

* [IfcConvert] Added IfcWorkPlan to xml export

* [IfcConvert] Added IfcRelConnectsElements to xml export

* [IfcConvert] Added IfcRelConnectsElements to xml export

* [IfcConvert] Improved related and relating xml export
