Dependency on qt view objects and mount_sample

[marcus-oscarsson]

We are looking into making the mxcubeweb layer associated with the queue a little bit thinner and push down some code into mxcubecore. Its something we wanted to do for a while and its going to be a multi-step process.

One important step in the process would be to get rid of the tight coupling to the qt view objects. There is a good example in Sample.mount_sample:

mxcubecore/mxcubecore/queue_entry/base_queue_entry.py

Line 840 in e78be97

centring_method = view.listView().parent().parent().centring_method

It would already be good if we could start with Sample.mount_sample method. I would suggest to remove the view argument entirely and replace the setText with a signal. The centering method in the example above should be replaced with a setting variable accessible with ie. HWR.beamline.sample_view or similar.

This would require some testing on the Qt side, something I cant do with full coverage so we would need some help from you Qt developers here.
