Implement advanced skynet functions

- factor out own class for the iadsnetwork within the conflicttheater
- This class will handle all Skynet related things - no specific group_name handling necessary in future
- make iadsbuilding own TGO class because SAM & EWRs are Vehicle Groups. IADS Elements dont have any groups attached.
- added command center, connection node and power source as Ground objects which can be added by the campaign designer
- adjust lua generator to support new iads units
- parse the campaign yaml to get the iads network information
- use the range as fallback if no yaml information was found
- complete rewrite of the skynet lua script
- allow destruction of iads network to be persistent over all rounds
- modified the presetlocation handling: the wrapper PresetLocation for PointWithHeading now stores the original name from the campaign miz to have the ability to process campaign yaml configurations based on the ground unit
- Implementation of the UI representation for the IADS Network
- Give user the option to enable or disable advanced iads
- Extended the layout system: Implement Sub task handling to support PD
