Pop-up

[michaelKurowski]

Is your feature request related to a problem? Please describe.
A generic modal component

Describe the solution you'd like

• A component that accepts other component via children prop.
• Component should be closed upon clicking outside its area
• Component should popup on top of the application.
• There should be a gray overlay between popup and the main screen, when the popup is visible.
• Content should be centered and padded
• Pop-up should appear in the center
• Put it inside theme/components in its own, dedicated folder

Examples of pop-ups, keep in mind that this task is only about making the "frame" of the popup that accepts body. It's not about implementing each of below modals!
