Add vehicle depot to alerts

It would be useful to be able to have an alert when the vehicle depot finishes construction of a vehicle - even just a ding! the same way you get when research completes. Perhaps either a toggle for the whole building (a ding for each vehicle) or perhaps be able to set an alarm for a specific vehicle in the queue. So many times I queue up an excavator, then lose track micro-managing something elsewhere in my factory and come back to find the excavator has been sitting idle the last half-hour :(

It'd also be nice to have something for when a vehicles upgrader batch is done

can be very useful at the start when you build one by one or a group of vehicles for a new mining operation

Or make vehicles in queue already assignable to towers. The same way as holding Alt while increasing the vehicle number on a tower, it would be helpful to use Shift + vehicle increase button to assign vehicles from the construction queue.
