Creates a new GDesktopAppInfo based on a desktop file id.
A desktop file id is the basename of the desktop file, including the
.desktop extension. GIO is looking for a desktop file with this name
in the applications subdirectories of the XDG data
directories (i.e. the directories specified in the
XDG_DATA_HOME and XDG_DATA_DIRS environment
variables). GIO also supports the prefix-to-subdirectory mapping that is
described in the Menu Spec
(i.e. a desktop id of kde-foo.desktop will match
/usr/share/applications/kde/foo.desktop).
