IDF Assets Pack support v1.1 (#233)

* Updated Irondome support to IDF Assets Pack V1.1, which includes the David's Sling.

* Added an Israel 2017 faction with the David's Sling.

* IDF Assets Pack air defence presets and assets are now correctly removed from the faction when the mod is disabled.

* Removed the Iron Dome mod rocket launchers:
- "9M22U - 122mm Grad"
- "9M27F - 229mm Uragan"
- "9M55F - 300mm Smerch"

These were added to the Iron Dome Mod V1.2 in order for the radar to recognize them and be able to intercept them (these are limitations of DCS), so new rockets were added. However, they don't exist in the IDF Assets Pack.

* IronDome to IDF-Assets migration
