Re-arrange CfgVehicles config for buildings and buildables

- All buildables are grouped together now.
- Buildables can be used and found under "DayZ Epoch Buildables" in the editor now.
- Update scope of a few vehicles. Most base classes should be private or at least protected.
- Epoch Loot Container can be found under "DayZ Epoch Crates" in the editor now.
