54284188 - move old dragging methods

500 error NoChangeException on content update
too many requests when updating the translation for a line, should only be one when the line is done
moving a line still isn't taken into account
when there is no region there is still a region number
Need a better visualization for regions, the order doesn't give any information, takes too much space, and doesn't tell when a line is not bound to a region, a vertical line spanning the bound lines maybe?
moving a line in the same place triggers a useless request

Apart from that trying to input text is very chaotic, not sure what is happening, try to transcribe a text from scratch, including adding/removing/binding and unbinding lines in the region panel.
