Copy/Paste of elements in OSD layout

[error414]

Here is video to explain how to works: https://www.youtube.com/watch?v=-F0jJvEQK2w

It's a simple clipboard for layouts, it's easy to use. Two buttons copy and paste.

Copy: save curent layout to clipboard
Paste: apply layout from clipboard

Super simple.

This is really cool. I think a Clear OSD option would be nice too.

it's a good idea, just set all "isVisible" to false and then it's variant of "paste" functionality. easy to do. I will add it.

Clear functionality added, Buttons "paste" and "clear" send changes to FC, but for make changes permanents is still necessary to click to save button. I would say it's ok.

Devel brief: for copy array I used an old way "JSON.parse(JSON.stringify())", I didn't want to add next library to configurator, for example https://underscorejs.org/ . The library provided clone functionality. i think it's not needed to mess configurator with many libraries.
