the cumulative mode tries hard to never lose already assigned variable
values. the naive implementation turned assignments into additions,
which made the trivial construct "FOO = $$FOO" double the size of the
array each time it would be executed.
so instead let the assignments be assignments, and then re-add the
values that would be dropped.

I can't fully explain the backtrace, but connecting to
qtVersionsChanged() in ::init() and not the ctor is the correct thing to
do.

Fix compilation error introduced by a rebase
(12d6f03d)

nodeInstancePropertyChanged() is called for _every_ state switch ... so
the current assumption that it only reflects real changes does not hold.

Instead, use the orphaned sceneChanged() method to schedule redraws.
However, this still results in some overhead when switching to the base state
(sceneChanged() cannot decide whether it has to redraw all other states
or not).

Due to using QTextCursor::columnNumber() instead of
QTextCursor::positionInBlock(), a lot of code would not work correctly
when used with wrapped lines.

In addition, there was an issue with columnNumber() returning 0 right
after inserting a character before the last character of a line.
