Subject: Simplified and made generic the way the pickup is handled.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

I also made the range be taken from the server type
as for the pickup and npc talk ranges.

Last but no least, I fixed the parameters sent with
PGMSG_PICKUP to send the (item) position where to pickup at
as described in the manaserv protocol.

The pickup is still not 100% functional due certainly
to two problems:
1. The client item coordinates might not be the exact same as in the server.
2. The client seems to try to pick up the item a bit too soon,
probably for the reason given in 1.

I'll investigate this in another patch.
