Playout inconsistencies with textarea newlines

[petterw03]

If using the textarea field type and json dataformat, newlines are parsed differently depending on if play or update command is used.

Template definition:

  window.SPXGCTemplateDefinition = {
      "description": "Textarea test",
      "playserver": "OVERLAY",
      "playchannel": "1",
      "playlayer": "10",
      "webplayout": "10",
      "steps" : "1",
      "out": "manual",
      "uicolor": "2",
      "dataformat": "json",
      "DataFields": [
        {
          "field": "f0",
          "ftype": "textarea",
          "title": "Content",
          "value": "",
        },
      ],
    };

Example input:

Value of f0 when using play: Test test test<br>Second line test

Value of f0 when using update: Test test test\nSecond line test

So on play(), the newline is converted to an escaped <br> tag, which seems to be happening here: https://github.com/TuomoKu/SPX-GC/blob/master/routes/routes-application.js#L1359-L1372

But for some reason, the same is not done on update(). This makes it hard to code template logic that detects newlines.

Yeah, update functionlity is difficult and may need custom logic per template. And as such, update functionality still is problematic on many levels. Will keep this here as a reminder for future updates.
