Add colouring to the output, having it enabled by default with CLI -c 

option to disable colouring

Resolves /Wizcorp/component-hint#50
hmmm colors or colours, i can see @ronkorving point. Best way to avoid this as @ronkorving said is to use something along the lines of -m  --monochrome, 'Disable colouring for text output' <- this way having the 'u' wont mess with american english (p.s. i prefer colour ;p)
