vcl: VectorGraphicSearch - support changing search string

Initial implementation only allowed to set the search string once.
This change allows to change the search string and still retain
the last position of a found string, so the search continues
from this positon forward or backwards. This mimicks how we search
through the GUI (which is the main use for this functionallity
anyway).
