being able to read/write the flashing finished technology

[Quezler]

i and others run into the limitation of not being able to set which technology "just got researched", there's a previous_technology on the force, but writing to it does not cause the technology button to flash, right now the most we can do is write the message to chat with the appropriate sound but it would be nice if we could trigger the flashing effect provided there is nothing next in the queue.

with normal technologies you can _kinda_ do it by setting it as the active research and then bumping the progress, but e.g. for trigger techs that won't work.
