Warning when leaving editor-mode

[Roelandsmith]

We need a warning: when you edited the code in the editor and you click back to 'block-screen' you lose all the edits you made in the code. So a little warning like: 'Do you want to save the changes you made?'

And also a dialogue box: like an instruction / verwachtingsmanagement: Blocks become code, but it doesn't work the other way around Blokken worden code, maar het werkt niet andersom.

Couple of questions @Roelandsmith: When do you want instruction to appear? When you switch to the code editor? Every time? This might get annoying to users. It's possible to add a checkbox: "Never show this again". This would add a bit of complexity of course, so would take a bit longer to program.

[Roelandsmith]

Good point. You want it when two things are TRUE:

• User is switching back to the Block-editor.
• User has non-saved changes in their code-screen code.

And -indeed- also a check-box 'don't show this again' would be great way to avoid annoyance. But that checkbox for now we can choose to postpone . It's a enhancement.

Notes to self:

• When the code editor is created, set it with the blockly-generated code if present, otherwise use the initial value of the code editor code, which should contain the default program
• Only set the originalCode field when saving, or loading a code project
• If the user intends to switch back to the blockly editor and hasChanges is true, show the dialog
• Give the user the options to continue to blockly editor, or remain in code editor
