radio buttons on ng modals should be consistent

[Cindy Lu]

The toggle button on ng create images modal is barely visible on the Default theme.

Please look at attachment.

It should be made to look like the same as on ng launch instance wizard - take a look at Source step - Delete Volume on Instance Delete.

    make toggle buttons look consistent on ng modals

    The issue is most apparent in this scenario:
    - Change to default theme
    - go to ng images panel
    - click on Create Image
    - the selected buttons don't have a box around it

    This patch makes the toggle buttons look consistent
    across ng Create Instance and Create Image modals.
