Copy and paste Apollon UML Diagrams in Multiple Formats to clipboard

[TobiasPr]

Is your feature request related to a problem?

Currently its not possible to copy and paste a diagram from one application to another e.g. one browser window to another.

Describe the solution you'd like

"Copy" should copy a diagram representation in different formats to the clipboard so that it can be pasted to any application. Supported formats:

• Apollon diagram representation
• SVG + png
• Microsoft Power Point Vector Graphic (optional)
• Apple Keynote Vector Graphic (optional)

Simple implementation is done -> copy json to clipboard write() (function to write arbitrary data to the clipboard) is not yet available in lib.dom.d.ts even though https://developer.mozilla.org/en-US/docs/Web/API/Clipboard_API
