Changes to how the command-aliases section works

[Lemvs]

Currently, there is no way to disable the default command aliases, or change the command format displayed in /is help and the COMMAND_USAGE message. That's why I propose that the command-aliases section allows you to set ALL command aliases, not just the additional ones, it's hard to describe in words, so here's an example:

If I create an alias 'discord' for the 'setdiscord' command, it will only be usable with the '/is discord' command,

but to also use it with the '/is setdiscord' command, you'll need to add 'setdiscord' to the aliases.

This change will allow you to remove default aliases if you don't need them, and choose which command alias will be displayed in /is help and in the COMMAND_USAGE message (the first alias on the list should be displayed there, in this case it would be 'discord', instead of 'setdiscord' as it currently is)

But now what if the command is not in the command-aliases section? Then it should have the default aliases that it had before.
