Dye/cloth items fixed, read description

Fixed Pet items too (they don't work yet, buy you can already give the
generators to you).
Fixed dye/cloth items, they change your actual dye/cloth. Be sure to
spell them right when you /give them to you.
Also, I just gave a look to the SellableObject class, I think I could
give it a try and fix Merchants (in a very BASIC way, like no rotation
or so... I may add a table to MySQL - no Redis yet, I don't like it -
with rotation sets to be read by a Merchant class and make it change the
SellableObject it returns to the one specified in the rotation info...
might make a table for guilds too and see what I can do, I have no idea
on how to make the client display the guild name on the topleft/player
tab at bottomright corners thought).
