* new errors for richembed yay

Simplified the parsing for color arrays.

Throwing some errors on values that would result in Bad Requests.

Changed setAuthor and setFooter's icon parameter to icon_url to match
the embed object's property name.

Changed the docs for setFooter to reflect that icon_url is optional.

* changed docs instead of arg names

* capitalization
