Changes for version 0.91.0:
- Fixed behavior on virtual desktops with multiple monitors.
- Added saving and restoring of window geometry.
- On X11, the fullscreen mode now goes via the window manager instead of switching to override-redirect mode.
- On Windows, in the virtual cosmos, replaced all the static disk drive items and the home dir item by a single file system item which dynamically lists all available drives.
- Minor fixes.
