theme-ui based components library

[atanasster]

(I think discussions are for such subjects, lmk if not?)

Part of my project, ended up writing a collection of theme-ui-based components. I saw sometimes theme-ui users asking for additional components, so here it is:

live: https://component-controls.com/api/components/actionbar/
git: https://github.com/ccontrols/component-controls/tree/master/ui/components

Feedback is very welcome, it's still a very early version and would love to clean it up.
