Customize @On Decorator

[Alfred Emsenhuber]

Adding the ability to further narrow down the On decorator.
Example:

@On('message','begins','!Foo') // Message begins with !Foo
private onCommandFoo(message: Message){
    // ...
}

@On('message','equals','!help') // Message equals !help
private onCommandHelp(message: Message){
    // ...
}

@On('message','contains','#bar') // Message contains #bar
private onHashtagBar(message: Message){
    // ...
}

This way instead of having one onMessage method which has to handle all commands that a user could send, there could be multiple methods for different commands.

I have made a pull request regarding this feature. Maybe you can link the request to this issue.

I implemented the @guard (and the Prefix function) decorator !
The documentation is here! :)
