Subject: [PATCH] gsettings: check $XDG_DATA_HOME for schemas

Add $XDG_DATA_HOME/glib-2.0/schemas as a schema source, after (higher
priority than) $XDG_DATA_DIRS/glib-2.0/schemas but before
$GSETTINGS_SCHEMA_DIR. This is per the XDG Base Directory Specification,
which states that user specific versions of data in $XDG_DATA_DIRS can
be created in $XDG_DATA_HOME.
