Set navigation bar color to dark on dark theme (#3091) * Allow overriding ConversationsTheme.Dark This change splits the dark theme style into two styles - base that stays the same in all configurations and Dark - the original - that can be overridden in specific configurations to add version specific styles. * Set navigation bar color to dark on dark theme Use secondary background color as navigation bar color when using dark theme. This avoids mismatched white colors on certain system themes. 2018-06-25 17:40:37 +00:00			`<?xml version="1.0" encoding="utf-8"?>`
