Code generation from Blockly broken on Blockly API v9.3.0+

[Jaronimous]

For the generation of code from the Blockly workspace to the Monaco text environment, which is part of the BSc Project in the branch bscproject_jchin, the Blockly API function [Block].getDescendants() is used to get all children and connections from a starting block, so that the adequate code can be generated for all active blocks in the Blockly workspace. The functionality of this function has changed since API version 9.3.0 to only show the children, and not the blocks connected to the children.

For example, when using the State Machine language, if there's a workspace containing a starting block machine 'a' with a state state 'b' and two transitions on 'c' to 'd' and on 'e' to 'f', the code generation using API version 9.2.1 will show the following:
machine a state b { on c to d on e to f }

But since API version 9.3.0, it will only show this:
machine a state b { on c to d }

A quick fix for this issue is to use the latest version of the Blockly API before 9.3.0, which is 9.2.1, but a more sustainable solution would be to rewrite the code generation part, so that it either adapts to the new getDescendants() functionality or to manually traverse through all children and connections.
