Feature: support alpha transparency #10

Closed daattali closed 7 years ago

As pointed to me in my blog post, it looks like R supports #RGBA, so that can be added as another feature to colourInput

It looks like CSS4 will support RGBA hex colour notation, which makes me more comfortable in implementing this. Make sure all formats work: 3/4/6/8 digit version. http://dev.w3.org/csswg/css-color/#hex-notation
