Commandpalette Proof of Concept

[zormit]

With the help of @anjakefala and @saulpw I've created this little prototype for #247.

Here's a demo that shows how it works, https://asciinema.org/a/616455. Notes on the features demonstrated:

• space opens the palette (as previously the plain "command name")
• if you type a digit, it'll execute the corresponding command
• the debug mode shows you the current weighting of the matches (oops, forgot to demonstrate with this one. See older recording for that)
• it's possible to adapt the number of matches (also check older recording for a demo. or use the option yourself)

I've decided to port over the fzf algorithm for this, such that we can do this without dependencies.

@saulpw i think this is ready for review from my point of view. There's one TODO left that I won't manage to finish today, but feel free to move the keystrokes around if want to have it in this PR :) My head is already fuzzy from all the fuzziness.

PS: just seeing that the tests are failing. Not sure what's going on there. But I'll be logging off for today, sorry! 🙈

This is great, @zormit! Thanks so much for putting the time into this.
