Allow an action to get a copy of the logs raised during the action.

[julianstirling]

For very long running tasks with lots of things happening (such as scanning on the OpenFlexure microscope) it is useful to be able to save a copy of the logs for a specific action along with the data created during the action.

This adds a function built into the Thing class to allow the action to retrieve its logs.
