        better default row detection ( associated with fdo#55621 )

        previous patch associated with fdo#55621 compared single instances of
row
        heights to determine the default height, it didn't take into account
though
        repeated rows. Additionally the limit of rows heights ( where rows were
empty )
        considered when exporting xlsx was the old 65535 limit.

On a Ubuntu 14.04 VirtualBox machine the commit before this saves the example
file in about 3 secs:

But with this it takes about 13 secs. Clickable link to the suspected commit:
