Leviathan with magnet.

Features:
Two options for magnet behavior (MagnetAlwaysEnabled in ini). Default is = 1 — magnet is always present (will appear when you get into the helicopter). If you put =0 then the magnet will appear after pressing the Home key. By pressing it again, you can remove it (the key is defined in .ini — MagnetEnableKey);
Helicopter power (thrust) can be changed in .ini — Thrust parameter. Default is 1.3, and in regular GTA SA it is 0.3. That's why it was not able to lift anything.
Mod is disabled in Up Up and Away mission

No more conflicts with mods that use modified handling.cfg
