Sticky editor toolbar

[Euthymious]

It would be great to have the editor toolbar sticky on small screens, just like tiddler titles are.

Oww.. this is a difficult one, @Euthymious, it's not something I can confidently apply to this theme in particular, because position:sticky styling sort of breaks when the div above it is also sticky or fixed, but has variable height. The height varies by the amount of buttons the user have installed either in edit or view modes... these are things I can't control.

Still I'll think about an implementation.
