Title: Adds an optional alpha parameter to the css_rgba method.

In order to resolve a transparency issue that arose through using a hex based value, I used your gem to convert the hex to RGB.

Though the gem offered one method for converting to percentage based integers, the alpha was hard coded to 1 and I required 0.6. On this basis I added an optional alpha parameter that defaults to 1.

I hope you find this useful :)
