White color filter should be added to expandable action icons

[afollestad]

This is a notification from an OTA beta testing system in one of my apps. There should be a little download icon next to the "Download" text, but it's a black icon. AcDisplay should add a white color filter to expandable action icons when the black background is enabled in order to make it visible.

Yeah, but forcing white color may break colorful action icons (which are really bad)...

[afollestad]

Well, they shouldn't ever be colorful. They're by the design guidelines supposed to be white on Jellybean/KitKat, and black on Lollipop (based on the background color of the notification itself). @AChep

Same with the actual app icons, they should always be white, since the status bar is always a dark color.
