Feature Request: Prioritize drone charging for drones with tasks

[hurzburz]

Hey,

so I rebuild my factory and one thing that I see over and over is that once hundreds of drones finish their work and return to a port to charge they will basically block any drone that also needs to charge there but has an active task. This means that placing anything can take a long time even if the drone is right next to the construction site because all other drones on the port follow first come first serve pattern I assume. Drones should be smart enough to let drones with tasks skip the line.
