Add function in net singleton to be able to bridge net singleton and DCS Scripting Engine

[TEMPEST.114]

At the moment the only commonality between the data extracted using the net singleton and the DCS Scripting Engine is the PLAYER NAME.

This means, that unless the user / mission creator is keeping track of all player names, then it's impossible to link the data from the net singleton back into the DCS Scripting Engine.

e.g.

There is no way to link PLAYER NAME and SLOT data back to the UNITID in the DCS Scripting Engine.
