[Mono-list] ListViewItemSorter property for FileDialog to folow .Net functions

[Petit Eric]

Hi
i add the listview item comparer for FileDialog, like this in a FSdlg,
yu can click to a collumn header (details view) to change the order,
like in .NET.
a perfect think, should be to add "order by group".

At this time, this patch provide similar way as .NET, except for one
thing, with .NET that work as it, yu click on the first column header
it  order asc and class by the first column item, yu click on the 2th
column header, it order asc and class by the 2th clm header.
Mine patch, change order asc/desc, each time yu click on a column, it
will need to copy paste my method for each column and dont continu to
use the same click event void to use my order function/class.
