Core/PacketIO: Updated CMSG_PET_NAME_QUERY structure and opcode.
Updated SMSG_PET_NAME_QUERY_RESPONSE structure and opcode.
Fix line ending that was making Debian go nuts.

Signed-off-by: SkyFire <admin@projectskyfire.org>
Fix: Guild vendors, guild charter buy, buy items and buy items errors.

Added opcodes and structures for the features listed above. Guild vendors need update db info.
I'm pretty sure Guilds have change too and all arena charter is unused now.
Now you can buy items.
Next Guild creation :)
