from Shinsuke Irie (irie) with some minor edits.
Shinsuke's description from the tracker:
---
I have implemented GVFS framework support of blender-thumbnailer.py which allows some file managers like Nautilus and Thunar to show thumbnails in trash or network directories. If Python's gio module is available, the thumbnailer uses it to access to filesystems mounted via GVFS. This change shouldn't affect desktop environments other than GNOME and XFCE.
A function gvfs_open() in this patch is defined to solve a stupid incompatibility between Python file object and GIO Seekable object.
On Ubuntu 10.10, I confirmed thumbnails can be generated for file://, trash://, sftp://, and smb://.
dlltool --> build_files/make/dlltool
bin --> release/bin
Since dlltool is only used make + mingw and ./bin is misleading because it would seem the blender binary would be copied there, but its just used for home directory files.
updated scons/cmake/make
