Regression: Multiple Cursor behaviour

Related to QTCREATORBUG-26503

In previous version of Qt Creator when adding multiple cursors one would start in a direction and then all subsequent arrow key presses were relative to the starting direction.

For example : Pressing ALT + UP, UP, UP, DOWN would result in 2 additional cursors above the starting point (adding three then remove one).

The new behaviour in Qt Creator 6b2 behaves differently:
Pressing ALT + UP, UP, UP, DOWN would result in 3 additional cursors above the starting point and one below with a total of 5 cursors.
