//META{"name":"EmbedText"}*//

/* HOW TO USE:
  COMMAND: /embed (color:#000000) (title:"Title") Text Content
  Ex: /embed color:#ff0000 title:"This is the title" This is the text
    This will create an embed with a red color and with a title saying "This is the title" with textsaying "This is the text".
   Color can be any hex color.
   Title MUST be wrapped in double quotes.
   v2 will allow for both single and double quotes.
