Add read only mode as an option

The idea is that you will still be able to select the elements (to copy them or see the properties from the stats dialog) and save the scene to a file at any time.

• Add the action to the context menu: Read only (just like Zen mode)
• Hide the top center toolbar
• Hide the properties toolbar
• Hide the canvas background color
• Hide the reset canvas button
• Disallow deleting elements
• Disallow modifying elements (size, position, rotation, align, order, etc)
• Disallow pasting elements or styles
• Instead of selection it should pan the canvas when mouse down and drag on empty canvas
• Make the context menu contextual and only show minimal options applicable for readonly mode
  • Copy to clipboard as png
  • Copy to clipboard as SVG
  • show stats for Nerds
  • Exit readonly mode
• Update mobile view
• Add a shortcut for readonly mode

Yea, let’s start simple. Even if we get it wrong on the first try, it won’t be a big deal.

Had a discussion with @lipis regarding the same and we agreed to keep only one mode to start with. We can rename the read-only mode to view mode.

For collaboration view-only links and shareable view-only links, we can make the view-only mode irreversible.

And later we can add presentation mode as well if needed.

@dwelle what do you think?
