Classic UI for Forever

0.6.12
- Fixed the error on enemy cast bars ("cannot be indexed with secret keys"). Forever throws these from the client, past pcall, so the values are now checked before use instead of caught after.
- Fixed nine errors a session on the character sheet: the attribute box did arithmetic on stats the client had marked secret, which stopped the rest of the panel filling. A refused row now keeps what it last showed and everything else updates.
- /cui reports how many stat reads the client refused.
