Improve file filter

[will-moore]

This improves the filtering of figure files in the File > Open dialog as discussed at #146.

To test:

• Open the File > Open dialog
• Try filtering the files with multiple words as discussed in RFE: improved search for figures #146
• Files should appear in the filtered list if all search words are found in the figure name, regardless of order - splitting words on white-space.

Works as expected. Tested with the example delivered by the external user in #146. Ready to mrege.

Will be possible to create a common method instead of having the same code twice?

[will-moore]

You're seeing the code changes twice because the concatenated js file is also committed.

I see. Missed that
