Add search through files and dirs in current directory

[SweetyAngel]

To search, just type letters of your file while being in file explorer. Use Alt+R to clear search and Backspace to delete last symbol of query.

I will check this tomorrow, great proposal!

I think a more ideal integration would be having a fuzzy search instead of a begins_with, and having the matched letters be highlighted in bold/italic/whatever styling RichTextLabel supports

Fuzzy search and search results highlighting were implemented. You can check them and merge it into repo.
