Consider always using 'Title' field from DIZ SAUCE records

The description (e.g. from a .tic or from the text part of a DIZ) might not be a good short file description while the SAUCE 'Title' field may be. See fire-39.zip for example.

The SAUCE field might be good to use instead, in some cases: | Title | Character [3] | 35 | The title of the file. | no | 00.0 |

Maybe an a per-directory option to import these.

file_sauce_hfields() currently does not use the Title file from the SAUCE record if the description (otherwise provided/parsed) is non-blank.
