Merge pull request #5303 from RosettaCommons/roccomoretti/membrane_in_pose
Move old-style membrane info printing from tracer to Pose.
Turn the noisy membrane output to debug level, and stick the info in the pose instead. The most recent set of info gets overwritten in the pose. In-Tracer output can be recovered with the option `-out:levels core.scoring.MembranePotential:debug`.
To enable this in an easy-to-use fashion, Pose comments are now written to output PDBs when they're present. (They were already included in silent files.) Pose-comment read-in is still controlled by an option.
