[DGD] Aliases & Stacked commands

[dannic at orpgs.com]

When I originally looked into creating an alias function for Karealia, I found
that 98 percent of users use a client which can handle aliasing on the client
side.  Decided that only commands used in some frequency would get aliased and
if a player wants to alias a set of commands they can use their client.

Maybe this isn't exactly a proper way to treat prosepective users but it has
been a good idea on my part.
