Misused barTintColor when setting up UI

[eimantas]

Setting barTintColor on LIFEAppearance proxy messes up UI if the barTintColor is black.

I have these two colors:

• primary color: 0x6CA130
• accent color: 0x252424

Setting them as either tint/barTint or barTint/tint colors respectively doesn't yield nice results because setting barTintColor sets the text tint for action buttons in an alert view that is present once user shakes the device AND sets the background color for image editor.

Possible solution might be introducing either backgroundTintColor OR not setting the text to barTintColor, but rather using tintColor.
