Fuzzy text search matching

[james-s-w-clark]

For the following example structure, I can search:

• MainGui // 3 results

It would be nice if we could do fuzzy matching, like:

• mgc // shows MainGuiController

As an aside (maybe this should be a separte ticket): text filtering is only on filenames. It would be nice to filter on modules/packages. The following search gives 0 results:

• src // 0 results
