Add support for minimum "box" size

[GoogleCodeExporter]

Often, users will try to 'cancel' a dragzoom operation by resizing their
selected rectangle to a point. Instead of not zooming, the map in fact
zooms the maximum amount.

Attached is a patch against r522 that:
 * Adds a new option, 'opts_other.minDragSize' specifying a minimum size in
pixels for the dragged rectangle. The default is 0 (current behaviour) but
something like 3-5 is sensible for most cases.
 * Ignores a zoom if the rectangle is smaller than minDragSize.
