crane sync

can all the cranes pick up at the same time (or a global settings toggle). for all the OCD people, having them out of sync drives me crazy. it wouldnt affect their pickup since the belt gives everything enough time to flow through a row of them.

a benefit could be frame updates/calculations. all cranes on all buildings pick up at the same time. would that be better for single timing and batching of graphic processes. that they dont all need an individual timer?
