Returns the values associated with key under group_name as
integers.
If key cannot be found then null is returned and error is set to
G_KEY_FILE_ERROR_KEY_NOT_FOUND. Likewise, if the values associated
with key cannot be interpreted as integers, or are out of range for
#gint, then null is returned
and error is set to G_KEY_FILE_ERROR_INVALID_VALUE.
