Better support for width, height, padding, and margins on rounded 
<div>'s.

I support this as well. Often you might want to use a title, e.g <H2> 
with shaded background and nice Rico-rounded corners. You also need a 
bit of padding so that the title text doesn't butt right up against the 
side of the box.

With current Rico-corners you have to wrap the <H2> in a <DIV> (for 
example), Rico-round the <DIV>. Means having to create a whole new CSS 
class for the DIV so that it can do the background shading.

In addition to this, the radius should be an editable option, as well as 
support for floating and inline elements.

Attached is the diff of rico.js v1.1.2 required to create "varible width
curved borders" for the Rico.Corner.round() function. It is set in the
function options using cWidth (corner-width) option like so:

var roundCorners = Rico.Corner.round.bind(Rico.COrner);
roundCorners('a',{cWidth:'2'});

- The width must be between 0 and numSlices (currently 4)
- The value is Math.floor'ed to remove floats and convert to an int()
- The value is also in poxels as all calculations for rounding are suc
