include left and right border radius classes

[prime-time]

Overview:
We want to have a small border radius on just one side of a component, so I thought we may want to include new classes for this.

Screenshots/GIFs:

We want a border radius on just the left of "This District" and on the right of the search bar.

Testing:

• Unit tests
• Manual tests:
  • Chrome
  • Safari
  • IE10

Roll Out:

• Before merging:
  • Updated docs
  • Bumped version in package.json
    • Breaking change? Run npm version minor
    • Backward compatible change? Run npm version patch
    • Only changing documentation? All good. Skip this step.
• After merging:
  • Deployed updated docs (make deploy-docs)

Lines 3 to 8 in b31c957

	/**
	* Common border-radius definitions.
	*
	* Auto-generated file.
	* To re-generate, run `make border-radius-styles`
	*/

Seems like this file is auto generated, can you make changes to the script that generated it vs to the file directly?
