Add a way to adjust text color in the richeditor

[zdavis]

Please include more information in this issue so we know why we need this feature. What, exactly, are you trying to solve with this?

@zdavis Some callout text has mixed colors. To accomplish this in the most flexible way a RTE seemed like the best solution except for whatever reason the default colorpicker in the richeditor only supports its own specific bank of colors. That will not do so I want to either edit those available colors or create paragraph styles, or whathaveyou, that include the manifold brand colors.
