Continuation of #48 - updates models for gifts and letters
Based on our last meeting:
the primary focus on on GiftDescription and LetterDescription: descriptions of gifts + letters in narrative sources
for the sake of demonstration, also added a model for PreservedLetter
the models are quite minimal - you can create categories for gifts and letters, and add agents as the sender/addressee (perhaps those should also be left out?).
existing data is removed; like in #48, there is an issue that the existing data contains both preserved and described letters.
