sort in autofilter

Submitted by J.H.M. Dassen (Ray)

The following was requested as http://bugs.debian.org/415718 :

Package: gnumeric Version: 1.6.3-5 Severity: wishlist

Microsoft Excel 2003 has Sort Ascending and Sort Descending options in the autofilter dropdown (see http://www.exceltip.com/st/Sort_Ascending/Descending_While_Using_AutoFilter/726.html )

This allows for temporarily sorting all relevant rows by the column containing the autofilter dropdown.

This would be a helpful addition to Gnumeric.

Version: git master
