Separate btn-border-radius variables

Created by: martinbean

I found myself in a position recently where I needed to alter the border-radius of buttons for them to be more “pill”-like, but when I inspected the buttons.less, it appears as though buttons’ border-radius values are based on the @border-radius- variables.

It would be good if there were separate variables for specifying the border-radius of buttons. They could inherit from the @border-radius variables by default, but there’s a level of abstraction if folks like me do need to deviate away from the global @border-radius values. Something like this:

@btn-border-radius-base: @border-radius-base;
@btn-border-radius-large: @border-radius-large;
@btn-border-radius-small: @border-radius-small;

I’m happy to create a Pull Request for this feature if it’s deemed something that’s worthy of inclusion.
