Additional 'css styles' dropdown for images

Hi guys

Imagine I could pre-create a few 'styles' (= css classes), and that there would be a dropdown to select from these created styles in the insert/edit Image box:
- None (default)
- rounded edge
- Image aligned right
- image aligned left
- highlighted
- Black & white
- ... whatever we created

So imagine somewhere in the Styling Zone I create a new css-class called "Image aligned right" with:
border-radius: 10px; margin-left: 10px; box-shadow: 0px 10px 0px -5px #ACC9E2;

Then I would only need to make one adjustment here, and all images with said class in all quote/templates would be updated automatically... and widget-creators wouldn't need to struggle with any css code.

I'm no CSS master by any means, but it could really help us out to match the look & feel of our branding... The same could be done for tables by the way.
