Download screenshot option

[samelhusseini]

Add an optional context menu option to download a screenshot of blocks or the workspace.
This should trigger a download of a screenshot PNG of the block stack or group of blocks.

We should also consider serializing the xml into PNG metadata:
It would also be nice if dragging that same PNG onto the workspace loaded a copy of that stack onto the workspace.
In the case that it was a workspace screenshot, perhaps it should replace the entire workspace with that screenshot source.

@samelhusseini Here's the commit where I added this feature for App Inventor: mit-cml/appinventor-sources@8b749ef

Awesome, thanks for the link @ewpatton!

Is this still being considered? Would love this feature

@samelhusseini plugin candidate?

[samelhusseini]

Yes for sure. Simply adding what we have in a plugin is straightforward, however I don't think screenshot.js in Blockly is complete. For starters it doesn't support all browsers..
