Removed transforms in svg map

The transforms messed up the boundign boxes. It was only a few translation
transformations.
Disabled area calc (too slow) and related changes

The area calculation by constructing polygons was way too slow using
firefox, I do not know why. So instead I resorted to using bounding boxes
only. I did some tweaks on the values and expressions used to calculate
whether highlighting is needed.
Added zoom-in during play

If the country location is used as help, the map will zoom in on the
current country whne playing.
