Ballas and GSF Shootout in Canyon Mod

The Ballas announced to the Grove Streeters the shooter in the Canyon. You have two options - help the brothers or be a Straight Buster, as Ryder said - go to the side of the Ballas.

Version V2:
Now that's a mission
Code update and optimization
Added a marker on the map, (green man) to find the mission.
A sphere has been added, if you step on it, the mission begins.
If all the ballas are killed, the script clears the remnants of the missions, which clears the memory.
Added 1 more backup car for ballas.
Crash fix.
Mini cutscenes.
Pickups of health, armor (to get them, you have to be a real kamikaze) and pickups of various weapons at the entrance to the canyon.
You better protect your brothers or the mission will fail!
You can start the mission again if you failed.
Fixes, fixes, fixes...
Please read readme first, it's important.
