**Task**
In the prototype, display text lines the following way:
[] the order of the columns is `other version, your version` (i.e. older is to the left, newer to the right, just like it is on diff page)
[] no changes in the text: As one box that goes over the whole width of the page, greyed out
[] conflicting changes: As boxes next to each other, on a per-line basis, with the color code yellow/blue as it exists on the diff page
[] For the first version of this feature, we don't differentiate between empty and filled line treatment
**Overall mock:**
For some reason it is always a mystery, but if you click on it, it resolves itself

**Notes**
- For implementation we need a config switch that allows switching between classes of currently used TwoColConflict and the new version of TwoColConflict
- There is already a class that creates an array of line change comparisons. This could be a good source for creating the view, just keep on the lookout what it does to newlines
