Match TFEDD button designs with EDD button color options

[SeanTOSCD]

As of now, TFEDD overrides the default blue button color/style for EDD buttons as well as the green button selection.

If a user selects anything other than blue or green for their EDD button styles, default EDD style buttons will show. That means no white background, a border radius, etc.

Button colors with the TFEDD style need to be built into the CSS for use when the user changes their EDD button colors. The button colors should keep their structure but match the colors for all EDD button selections.
