#10 show all files option for open file dialogs

[Andrew Bibb]

Option to show all files has been added to the open file
dialogs. Without this patch you will only be able to see
files with the extensions *.dwg *.DWG *.dxf or *.DXF.

If you had a drawing such as "mydrawing.dWG" it would
not show up in the dialog. To get around this download
the patch, recompile and you will then be able to select
"All Files" as an option and then select the oddly named
one.
