Title: Fix calculation of height of frozen column header

When for example using a 2px bottom border on `.ui-jqgrid-hdiv` the height of a frozen column header is not calculated correctly.

The outerHeight of the surrounding `div` should be used to calculate the height.

I fixed this issue in this pull request.
