Success and Warning buttons need appropriate color contrast with active/focus

[joshuasosa]

Problem/Motivation

Text on backgrounds should have sufficient color contrast to meet WCAG AA for normal text.

Describe the bug

In the currently published Bootstrap version (2.0?), the buttons for Success and Warning types get the wrong text color when their state is 'active' or 'focus', such as when clicking on them.

To Reproduce

Click on the Success or Warning buttons to see the color change as the button is clicked. Or use inspector tools to manually set Success or Warning button status to active or focus.

Proposed resolution

Copy over the same styling used in the hover state for these buttons. Or consolidate active/focus specification into the hover statement.

Expected behavior

Success buttons for Success and Warning should retain their respective 'hover' state text color.

Screenshots

Success and Warning are 'active'

Colors fail for normal text
