UH-60L mod support

Resolves #1964 but adding CTLD will require the use of Liberation plugins and thus are not included in this pull request.

- Implemented support for the UH-60L mod by =X51= Kinkkujuustovoileipa, Cubeboy, Jonas, JinxxDCS, Dorian, =X51= Parzival & =X51= Lawson.
- Because the standard DCS tankers will not fly below 160ish knots, the UH-60L mod team have included a modified version of the KC-130 tanker designed for refueling at speeds of 120-130kts.
