Button Groups not rounding correct corners at certain view widths.

[atclarkson]

When screen is tablet or desktop width and the buttons are stacked, all in a column or 2 buttons over 1 button, the wrong corners are rounded. This takes away the seamless effect that was desired.

It looks like the first button of group always rounds the left side of button and the last button always rounds the right side.

Thanks for the info! This has been rectified as of commit cc11f37.

The prior button layout was too complicated to fix since the rounding really depended on how many buttons were next to each other on a smaller screen, so a column layout was used instead.
