Scipion-em-dynamo

- Subtomogram alignment: fix bug when using masks.
- Subtomogram alignment: fix output problem when the alignment removed some particles.

- Hot fix: one of the steps of the common list from the model workflow is not included in the Dynamo side. The plugin
now offers the same behavior, so this kind of models do not fail now.

- Model workflow able to generate correct (coordinates of a model) and failed (meshes whose model workflow failed
and need to be fixed).
- Viewer adapted to this new scenario.
- The generation of the saving yes/no dialog window was adapted to the new scenario, too

- Fix test
- Dynamo version check message rewritten

- Alignment improvement: if dynamo fails, alignStep does not finish

- Protocol for importing subtomograms from Dynamo's .tbl files improved.
- Binning factor interpretation is now the same as in IMOD (followed by Scipion).
- Protocol for subtomograms alignment simplified.
* For developers:
- Tests expanded and re-factorized using the test centralization layer.
- Protocols for tomograms importing and subtomograms subboxing disabled (to be reviewed).
