Pre-release of hyp3e version 4.1.2

Features

Change the Weapon Proficiencies text field into an array of weapon names #331

This represents a change to the character sheet as well as the underlying data.
- The original idea evolved a lot as it was being developed and tested. Ultimately, the character sheet display of Favoured Weapons was changed to read-only, with a button to launch an app that allows for editing the weapons list.
- The character sheet display is in the same location, but consolidated from 4 fields down to 1 text area:
  - The book icon launches the edit app. The eraser icon to the right of the book clears the legacy data, which was migrated as part of the updated. Once used, this eraser button disappears.
- The Favoured Weapons editing app:
  - Most features should be self-explanatory.
    - Clicking Add inserts a new, blank weapon row to the Favoured Weapons section.
    - When adding a new weapon, Level Gained defaults to the character's current level. But it can be edited if necessary.
    - Checking and unchecking the Forbidden box will also move the weapon between the two lists.
The first time the world loads after this update, a migration script runs that tries to take the existing text fields and migrate them into standard weapon selections. It does this for each character-actor in the world, and produces an individual migration report in the world Journal. The report looks like this:
- The referee and players should use these reports to double-check all of their character migrations for accuracy.

Formerly a plain text field:
The next time the world is loaded, the system will migrate the existing spell list text to the proper selection from the list if possible.

This can be handy if the "Treasure" item is actually a pack mule, wagon, or other "container" that actually has a weight limit to what it can carry.

Use the NPC sheet for a beast of burden. Could even be done for a porter, or a wagon, etc.
Add the Carried Weight field, encumbrance alert text, and a Strength field so that encumbrance can be calculated the same way that it works for characters.
Only do this for NPCs, not Monsters. So the "Monster" toggle hides the weight and strength fields. But flip it back to "NPC" and those fields appear.
