BackButtonStyle doesn't follow header foreground #104

Closed timheuer closed 12 years ago

timheuer commented 12 years ago

In order to enable some automatic contrast determination of the header foreground (based on HeaderBrush), the BackButtonStyle needs to change to be smarter about it's colors used in the various states. Currently it relies on theme colors, which is generally good, but does not allow for some deterministic re-coloring based on contrast.
