Title: Add Button Groups to Pure

This PR adds horizontal button groups to pure, thereby fixing https://github.com/yui/pure/issues/126.

## Why we need button groups
I think button groups are a good way of grouping multiple buttons together to give them some sense of context. This can be useful in a variety of websites.

## How it works
The button groups are wrapped in an element with the `.pure-button-group` classname. This element inherits the styles from `.pure-g` to collapse the whitespace within it. The `.pure-button` elements within this reset the letter and word-spacing, similar to `.pure-u`.

## How it looks
