Basically done with converting Command2
Also moved the Minecraft part of the param converter to Command2MC, although the user object getter should be made more generic
Fixed bad permissions being used for subcommands (older change)
Updated Commodore and made it only register a command node once - this fixes main command argument handling as Bukkit's handler is removed
Added option to ignore the tab completion provided by the parameter type (param converter)
Only showing matching completions (it has to start with the text typed in)
