Implement option to define command alias

[WoozChucky]

Some commands have multiple alias such as /a , /advance, etc This way we can now optionally define alias for commands.

Altought alias are being used as a copy of the command itself when being registered, it provides a way to not need reflection when evaluating incoming commands at runtime.

[MeikelLP]

Can't we just put multiple [Command] attributes on a handler to solve that?
