Client -> Server
Client to Server communication is simple. Only thing you need to do is send (upper-case) command followed by its' arguments. I will be using following format:<arg> = required argument
[arg] = optional argument
<arg... = required text argument
[arg... = optional text argument
Text arguments starts with : and can contain spaces.
