core: implement fetch_command_def
This rovides an abstraction to fetch a worldedit command's definition, 
regardless of where it was registered.

We would normally expect all commands to be registered in 
wea_c.registered_commands, but before we only do a one-off pass to 
import commands from worldedit should a new mod we aren't aware of 
register a command with worldedit and get loaded after us, we won't 
detect it - hencee  the need for this function.
