add name to structure tree view

[alessandrofelder]

Description

What is this PR

• [ ] Bug fix
• [x] Addition of a new feature
• [ ] Other

Why is this PR needed? We'd like to see the names of the structures in the tree view, not just the acronyms

What does this PR do? Alternative, simpler-to-implement solution to a toggle between structure acronyms and names: acronyms are always shown, and names can be shown/hidden with a checkbox.

For the more difficult implementation

• make the model editable by reimplementingsetData (but make sure the user can't edit) or
• replace model entirely anytime things are toggled. This would work OK if we managed to remember the expanded indices, but this is tricky because we are left with dangling pointers on model replacement. See an attempt at this on the complex-structure-tree-view branch.
