#303 Brokers do not show the correct mouse over icon

mouse icon should be the stacks of coins(same as merchants)

this is based on the primary entity command

we use /itemsearch on brokers, that must not be the right entity command

eg. merchants use 'frommerchant' and guards use 'find npc' to set those special icons on the mouse

proper command is /frombroker

insert into commands set type=0,command='frombroker',subcommand='',handler=527;

update entity_commands set command='frombroker' where command_list_id=20;

other hardcoded commands:

1. loot
2. contest bank (two commands?)
3. find npc
4. alternate advancement
5. reforge
6. automentor
7. transcribe
8. create guild
9. heraldry
10. frombroker
11. tomerchant
12. achievements
13. repair
14. frommerchant
15. examine
16. pray
17. browse market (two commands?)
