Add ability to trigger initial contact and ready pre-contact (without the associated AI voicelines) via scripting

[ACS_Dev]

My suggestion/request:
  Create AAR functions that mission editors can call via (ideally) the default triggered actions menu in the mission editor or if necessary, via raw lua
  scripting.

  From my (limited) understanding of how the backend of the AAR process works these would be the initial approach call, the ready precontact call and the transfer complete call. I am confident these functions already exist in the context of the AAR script but I am asking for them to be made available for manual triggering.

The utility of this would be significant, particularly for scripted missions such as campaigns. Some like BD's R1DF have custom scripted comms leading up to the tanker but the player still has to make the final interactions via the generic and bland built-in radio items. Adding these functions would allow campaign creators to build their own seamless AAR events from start to finish with custom, unique voice lines, patterns and potentially other features. I know at some point there will be an AAR rework but I believe that if implemented and fully exploited by knowledgeable mission developers, the resulting product would consistently be higher fidelity than even ED's eventual AAR overhaul (namely in the variety and quality of voice lines).

I am not asking for an overhaul or new 3D model. All I want are functions that simply move the specified client aircraft from one step to another in the existing AAR process without triggering the default voice lines or on-screen text.

From a work load perspective I doubt adding these functions would take anywhere near the resources required for the AAR overhaul and would certainly help tide the player base over while we wait. Again, some implementations of custom AARs with these scripts could surpass ED's eventual AAR update.

From a business perspective giving mission editors the tools to create higher fidelity simulations in these areas makes paid DLC campaigns more attractive to customers and would likely result in additional cash flow to ED. There are other areas where this approach could be useful, especially with the similarly simplistic ATC and JTAC interactions.

Thanks for reading.
