Changes in Description

Add !name command and names database, pretty stupid command, but was
suggested by some trolls, basically selects random name from database
and assigns it to player, names can be added and removed from database
with !addname !clearname commands, added !rank, !addrank, !clearrank and
database, works the same way as !name but contains funny ranks, nerfed
flood protection, reverted banned ip's checking but made some fixes to
it, added ping_by_slot, not used for now but maybe wil be used later,
banned message warnings now in private chat, maybe other things i dont
remember...
