Remove terminal/ and the corresponding experiment
The terminal experiment was initially proposed in 2016 [1]. Since then, no maintenance work was performed on promoting the experiment to a stable feature. Closer inspection of the feature shows that it does not work. After enabling the experiment, issueing the command "Show Terminal" results in an internal error in xterm. If we want to reconsider this experiment, we should re-evaluate the approach and come up with a proper design for the feature. For now, I would propose on removing the dead code.
