Collate rageshakes from the same group ID under one issue (with subissues for each shake)

[Half-Shot]

Element Call features the ability to generate a unique ID, and share it with other clients when generating a rageshake so that all shakes can be grouped together when debugging. I'd like it so that this would create one issue, with a sub issue for each child shake.

I suspect the best way to do this would be to introduce a standard identifier for grouping shakes, and have the code automatically append subissues to an existing issue if the ID exists. This might require trace amounts of persistence, however.
