feat(config): defaultEmbed accepts colour arguments. #374

* added parameter `color` 

Changed the `defaultEmbed()` function so as to have a parameter for **color** that is defaulted to `#0099ff` color (blue).

This change is in response to Issue #372,

* removed type of color

The linting suggested I remove the type from the parameter as it is inferred.
