Two truck-dumpsters simultaneously active and landfill working

@bballtwenty8 
Working simultaneous trucks, two paths of A star not getting displayed, 
Landfill tile getting overlapped by path "*" when Landfill is selected.

@noahdela 
Updated the truck code with the fuel_filled as global? I did that, you forgot to push.

Let's merge this after we test it and then only two things remain:
1. Update truck's trash levels
2. Update truck's status

They will be able to start working again.
Thanks,
Forgot my pi.  Have to go back.  You can fix this it's your module.  Be
back in 20.
