Add a fuzzy search dialog

[treagod]

This implements a fuzzy search to solve #134.

I adapted the fuzzy search from this blog and integrated it into a modal, which can be opened with Ctrl+p,

For now I want to implement the search as a plugin so that the user can opt-in as long the fuzzy search is not mature enough - but I think in the long run this functionality should be part of the core of the editor.

Are you still working on this? I'd be glad to help if you need to.
