Cut off options' path label

[hryniuk]

Serin's comment on #159:

When loading the options file, a label at the bottom has text set to a file path. If the path is long, the whole window expands to allow it to be displayed. The effect is quite jarring, and very long paths could cause problems, so I think the path should be cut off, or the label should have multiple lines.

I think we'd rather implement #190 and then we'll remove that label - options filename could be displayed in options editor and there could be just enough path's parts to differentiate them. For example:

• after loading $HOME/Wangscape/doc/examples/example1/example_options.json:
  • example_options
• after loading $HOME/Wangscape/doc/examples/example1/example_options_back.json
  • example_options
  • example_options_back
• after loading $HOME/Wangscape/doc/examples/example2/example_options.json
  • example1/example_options
  • example1/example_options_back
  • example2/example_options.

Or, even, it can be made a hierarchy in a list, so:

• example1/
  • example_options
  • example_options_back
• example2/example_options.

Full path could be shown after hovering them.
