Text blocks jumping around in the wiki

[FlorianMarquardt]

Expected behaviour: The wiki text changes only minimally, e.g. when I drag objects to update coordinates.

Observed: Sometimes for no good reason whole text blocks jump to the wrong position. I believe this is when I use '#' to mark sections/boxes. Maybe it is even tied to my attempts to use '##' for nested blocks.

In the original version, the program only modified the minimal pieces of text required during dragging etc.

To allow the nested hierarchy, links immediately below a block tag (i.e. # ...) are considered inside the block; another box tag with an additional # will be nested inside.

When a block is dragged and dropped inside another block, its entire code should be moved inside the new block, in particular below all the links that it contains.

I believe there is a bug when one starts a line with # but then it does not put the complete tag # ...
