#937 Eliminate 'sf'/shortfiction dropdown choice

[Ahasuerus]

In the Content section of NewPub/EditPub/AddPub/ClonePub forms, the "storylen" dropdown list is typically limited to four choices: "-", "shortstory", "novella", "novelette". However, sometimes a fifth choice, "shortfiction", appears. Also, when "-" is filed for a SHORTFICTION title, the software puts "sf" in the "storylen" field.

We need to change the display logic not to display "shortfiction" as a choice in dropdown lists. We also need to change the filing logic not to file "sf" in the database. The software already displays the word "shortfiction" for SHORTFICTION titles without a storylen code.
