DiscordSRV Ultimate

Security fix - the message cannot contain placeholders now IF its separated from the rest with : or »

New placeholder: dsu_asciionly_msg. This is used to remove all non-ASCII characters from a string, for example emojis.

(Note: Actually this isn't ASCII but this: QWERTYUIOPASDFGHJKLZXCVBNMqwertyuiopasdfghjklzxcvbnm!@#$%^&*()-=[]{}();':\",./<>?)

Initial release!
