World generation in maintenance module now pre-computes the space-padded world name, up to 16 characters per AP limits, instead of padding on each output - resolves #61 (closed).
Also, selective about using the padded world name is optimal for readability; all other places use unpadded name:
- Item receiver in items / priority channel
- Item sender in hints channel
Also, fixes some bugs with hint tracking:
- "Found" reactions to hint messages use correct channel
- Hints for receivers (incoming) correctly
- Hints list more clearly indicates which hints are incoming items, and which are outgoing items
