This change restores the system gallery theme ID to bullets.thm, which
restores language and localization-independent lookup in the gallery UI.
This field was unintentionally removed by a prior update to the file
contents. Updating these .thm files is unnecessarily fragile. There does
not appear to be any way to set an ID other than by using a hex editor,
and the ID field is only retained if updates are incremental. In order
to make this somewhat easier, this change also adds an --id <id>
parameter to gengal. This parameter can be used to manually set the
correct ID when a new .thm file is generated (however, it will not
change the ID for an existing .thm file that is being updated).
