Improved search/sort in dialogs

[gsteinLTU]

Searching in dialogs (e.g. project open) could be improved by being more fuzzy. Students are pretty likely to make typos (part of the motivation for block-based programming) so showing no results if they type "MyProjct" instead of "MyProject" could be frustrating. Something like how the search on extensions.netsblox.org works might be better.

Currently, the sorting for project names puts e.g. "Untitled (20)" directly after "Untitled (2)", before "Untitled (3)". It might make sense to improve the sort function used to be aware of NetsBlox's naming scheme. Having multiple sorting schemes available could be useful too, "most recent" is likely more useful than alphabetical, especially for students working on assignments.
