[crossfire] New DM command

[Nicolas Weeger]

Hello.

Since there was no commit mail (i killed CVS when i saw it was
committing archetypes files, but it had already committed other files),
I'll just point out there's a new DM command, "insert_into". It takes 2
arguments, and puts the 2nd in the 1st's inventory.

Pretty simple.

Note that you can't put a player in something, to avoid weird issues :)

Note that I haven't checked all cases for updating object's information,
if something is weird tell me and I'll fix.

Nicolas
