Reworked autoassigner (improved limits between required secondary and
surplus primary stats). Hero's will removes most of diseases, tonic
removes slow. Added visual info for collected NX cards. Added commands
cake (cake boss with customizable HP) and setgmlevel. Reworked Trade
system now checking for slots smartly (instead of just checking for
empty slots).
Implemented Guild PQ. Fixed a problem introduced earlier where negative
EXP would be deemed as "integer overflow", provoking many game breaking
issues as result.
Made NPCs now work properly on multiworld system. Solved multiple issues
regarding Player Shops not giving back items properly when owner exits.
Added restriction on changing channels at FM rooms, preventing shop
owner entering Cash Shop.
